Changelog For scikit-rf
Generated on 2013-01-30 08:05
-------------------------------- v0.13 ---------------------------------
alex arsenovic (146):
added a Frequency.npoints setter, which was accidently removed.
minor change to save_all_figs
fixing Frequency, and Network to accept arbitrary frequency vectors
minor change
last commit forgot to change the Frequency.copy() to allow for arbitrary f's
added option `Network.write_touchstone()` to toggle the writing of z0 in comments
fixed bug with Network.read_touchstone() when reading a complex z0 as written by skrf
added calibrationSet.py as a default import in calibration module
added a forgotten test file
added touchstone test coverage
fixed minor __mul__ bug in Network
fixed minor bug in media.
adding pickling ability to Network
adding pickling support
big IO changes with new pickling support
added pickling support to Media and RectangularWaveguide
working on IO. made change to Network constructor.
moving touchstone into io and fixing cirular depency problems.
fixed skiped test_touchstone test
added test files i forgot
added more flexible ways to construct `Network`
added __repr__ to Calibration
minor changes to repr strings
worked on calibration pickling, added `save_space` function
added new submodule `data` to hold data for examples and such rename media test case to be more consistent with rest of skrf modified picking command for Network
removed `has_run` property of Calibration, replaced its function with a try/except block
worked on calibration , and pickling of Media types the problem is that the ability to have propagation_constant and characteristic_impedance be functions prevents the possibility of pickling. Furthermore, it is confusing. perhaps i will solve this by re-structing the Media type
:qq
wrote `read_all`, and `write_all` functions
fixing Touchstone class to take file objects
minor
applied matts fix to vna.ZVA40.upload_cal_data
minor
minor
minor

Adding to plotting.smith() a MATLAB-like smith chart option
-------------------------------- v0.12 ---------------------------------
alex arsenovic (41):
removing old testCases/ directory, to follow numpy/scipy testing convention
Merge pull request #4 from treygreer/master
Merge branch 'master' of github.com:scikit-rf/scikit-rf
Merge branch 'master' into develop
removed old testCases/ dir again. moved modified testNetwork.py to tests/test_network.py
added a skip decorator to the rectangular waveguide test, because i know it fails (due to z0, and port impedance mismatch? i forgot)
modified README
moved 'z' and 'y' creation, to the accessing properties, as opposed to the assignment of 's'. this was done to increase speed as the s2y, s2z functions are slow.
added shunt_capacitor and shunt_inductor construction tests, because they dont work!
made a fix to media.load, which should work for number-like or array-like input.
added funtion for media to write its contents to a csv file. will probably add a read method as well.

fixed bug in networkSet.signature.
added class method of NetworkSet.from_zip() which will take a zipfile of touchstones and return a NetworkSet, of the files.
modified new NetworkSet.from_zip() to skip over files in archive, which fail to construct a network .

added a some transmission line calcs, still working up to standard defs.
added more wr functions, still havent fixed genWaveguideThru, mmm
more waveguide adjustments, added class waveguie, and made wr a subclass of that. in the future it would make sense to make a generic transmission line class which has as subclasses: waveguide, microstrip, coplanar, etc
small changes
shelled out some future classes. and discovered teh 180deg bug inteh genWaveguideThru was du to my mis-drawing of integration line in hfss for the waveports. then it took me 3 hrs to find my hack, that i forgot about !!
shelling out network code and basic mwave engineering stuff
still working towards one port cal
no errors, but one port osm not verified to work yet
minor changes. shelled out some calibration kit types but left as commented.
little things
added teh touchtone class, taken from dataplot project. it is very good. much better than my code. started to implement the correct form of a ntwk
fixed bugs in touchstone: used 360/pi for deg , whould be 180 used incorrect matrix representation, was transposed for what it should ahve been at any given frequency slice
added some plotting functions
more plotting stuff. its starting to come together.
comments
updateing code/ commenting / re-arranging
more changes. . .
huge changes, many deletions. need to break up files next. and do some testing.
moving/deleting
had to revert to version 58 because 59 missing ntwk(). fixed bugs.
changed waveguide std create type, its not a ntwk is the all the freq parameters in the ntwk type needed? made some convience improvements to ntwk.plot*, so one ports dont need to specify indecies.
fixed some calibrations ruitines to be able to take ntwk instance. started to change the vna vi, probably broke it.
just learned about how to copy a class. used this in returning a new ntwk () instance for the applyABC function . might want to make a ntwk.copy.
minor changes

moving things arround. started createImpedanceStep()
got impedance step working and fixed returned shape for createDelay
added some simple lumped element functions so that i can model waveguide discontinuties from marcuvitz
finished getABCLeastSquares. looking at wiki for moore-penrose psuedo-inverse, and travis oliplants scipy tutorial made this easy. also this has a nice connection to geometric algebra, which i have yet to understand.
added deEmbed1Port, which is really the same thing as applyABC.
working on cals

added isReciprocal and abc2CoefsDict
made ntwk and new style class and started to implement property's
added a time domain transform for ntwk object,it might be a good idea to define the freq some other way also defined a changeFreqUnit function for ntwk. need to change all of the members of ntwk to propertys eventually
added conductor loss functions to waveguide class.
added an example for calculating waveguide loss chart
updated examples
changed version label, (should automate this so it doesnt have to be updated)
fixed example and more waveguide loss fixed
minor
starting calKit class. maybe a different name would be appropriate
finished ( for now) the calibration class. coefficients are only calculated, if they havent been before, so if a kit is updated then calibration.calculateCoefs() must be run again.
minor
minor
added a new one port cal method, alexCal, but it shows no benefit to the standard algorithm, other than it only inverts a 2x2 matrix.
started to add SDDL calibration, for unkown lengths of delays
sddlCal is working, and cool. need to make a version which assumes more of a model, than just mag=1. like the first implemenation, which assumes a offset short of unkown length. this will prevent effects of badly known standards. also, comparing the two techniques will produces more inciteful information, such as accuracy of assumed model.
<none>
added sddl1 and sddl2 to the calibration types accepted by class calibration.
adjusted calibration type, for sddl cals, so that it saves the auto-cal'd standards,
wrote sdddd2 but have not seen it converge to a very low residual value, still at 700's. possible reasons: function is not well behaved, so minimizing wont be so easy the delay shorts are not good models the wg class is not good enough
working on sddl and sdddd
added some plotting functions to illustrate evolution of iterative calibration methods
<none>
added averge function as a class method to ntwk class
more work on sdd* cals
added sdddd2UnknownLoss and am fiddling with sdddd2
sdddd2UnkownLoss works
added a resizeFreq function so that networks of different number of points can operate on each other for de-embeding, etc
but resizeFreq dont work yet, so i have it raise a NotImplimented exception
removed superfolus code in getABCLeastSqaures and renamed it to onePortCal. recently discovered that the auto-cals are well known techniques. its called non-linear least squares and its available in scipy.
re-wrote getABCLeastSquares and renamed it onePortCal
start writing transmissionLine super class and freespace
more work on transmissionLine
wrote a frequencyBand class, just to suport transmissionLine functions which require frequency band info, so a transmissionLine class can be assigned a frequencyBand, this way we dont have to redudantly supply this info
workign on transmissionLine methods
minor?
fixed minor indentation error
working on onePortNLS
finally fixed the classmethod errors in transmission line. the problem was that class attributes are different from instance attributes. and a class method must not access instance attributes by default.
broke up the main file, qualified some imports
tried to make a freespacePointSource class for 1/r^2 dependence, ran out of interest.
added a mobius class for the mobius transformation, which could replace reflection coefficient, and some other things ... also looked at the alexCal, have some error, which i didnt notice before about when the ideal standard is a match, whcih causes an inf because i have 1/a1-1/a2 no sure what to do about this yet
got onePortNLS working thanks to new functions scalar2complex and complex2scalar
minor unsure?
minor
<none>
sdx2 working and tested.
removed the NLS2 which is very hard to write because leastsq only takes 1D lists the problem with this is that my cals rely on calling a transmission line, method, createDelayShort.
minor fix on __init__, commenting in transmissionLine
comenting
changed mobius so it can take a characterizing matrix, h. also fixed waveguide.beta function so that it will produce an imaginary number below cutoff
added a freespaceWithAttenuation class to the transmission line bunch.
updated waveguide type to use frequencyBand type
still updated class for frequencyBand. also added matrix invertability test on onePortCal, might slow down iterative cals so this needs to be tested.
removeing old trunk
moved new branch in
moved testCases and the un-used mobius class to a testing folder, and consolodated the constants into the convenience file, which makes more sense anyway
i was edditing the branch on accident. so i am moving the changes over here.
accidentally cp'd virtualInstrument/__init__.py to transmissionslines
moved this to calibrations --This line, and those below, will be ignored--
had to fix some circular imports caused by consolidation of calibrationFunction sorted out
added a plotting.py file to hold smith chart, which needs major improvement
added docs, and a script to generate docs in teh future
added distutil related files
added the source distribution
added windows binary installer
fixed error in setup and added teh zip source disto
added setuptools to install, and registerd with PyPI, this should help with dependency
fixed minor bug (i think )
just commented out
updated install modules due to minor bug in vna.py
removed dist directory because its recursively includeing itself in build when i use setuptools
<none>
<none>
removed teh requires option because the compile of matplotlib through setuptools doesnt fucking work
started the manual.
added a beta versino of manual
added eps files
updateing stuff
working on docs
<none>
moving docs around. also looked into sphinx and epydoc. both are good and good for different things. the sphinx is more aestetically pleasing and cleaner, but the epydoc is easier and more thurogh
udpated docs and changed incorrect comments on doc strings
fixed minor bug in calibration/network referenceing. forgot what else.
added my variational models for waveguide discontinuities . these are subject to large changes, and are very imature
implemented the self-calibration using variational junction admittance.
added discontinuities module init
fixed bug in new cal algorithm
added parametertized standard class. this will allow one calibration routine to run for arbitrary parametrized standards making it so i dont have to re-hack it every time. also i modified variational methods
wrote the unified self-calibration algorithm, but have not tested yet.
working, working
decided to implement specific parameterized standards as classes.
working working
HACK HACK made a hack on the transmissionLine.RectangularWaveguide.propagation_constant so that WorkingBand can calculate the response of a line (or delay_short) without having to provide mode-information. really the WorkingBand is a TEM-Working band, otherwise all teh network creation functions would take mode-index parameters.
added a simple zva40 class needed for imeediate use
working on terminated variational expression. added a simple, PNAX class to virtualInstruments/vna used for drift testing.
workign working
need to fix all the matrix handling of waveguide functions, which sucks
updated docs
made some import changes to transmission line functions. i need to fix this conceptually.
fixed the junction admittance with termination, i needed to make assumption that region I was matched, otherwise the same termination boundary conditions are enforced as in region II.
created a new and more sensible variational function for aperture_field formulation its called aperture_field.
working on variational methods and parameterized standards.
fuck yea
making major fuckups in cascade and de-embeding functions, due to serious bug lihan pointed out. i have no idea how i could not have noticed this. it must be a mathematical anomaly.
started to add testcases, a long long time too late. ..
moved testing to beta
added testCases
removed redudant files , svn sucks
testing
added a good step up method
added a general rectangular junction, of which all the others will soon be put into terms with.
tested rectangular_junction againt rotated adn show agreemenet.
wrote a 8510c vi, without any testing. had to change an argument to the rectangular_junction because i want to use this as a function for my parameterized_standards, and they only work with non-iterable arguments. i could fix this. but not now.
probably messed up functionality working working
fixed a major bug in teh parametrix standard calibration. it could only handle stds with 2-parameters, due to my inability to count.
added some additive noise support. one is a method of Network, this is needed because you cant simply add phase noise without knowing the phase of the signal you are adding it too.
fixed network averaging function. it was a stupid error
not sure, probably minoro changes.
made some changes to 8510 vi
update vi's
added vna phase noise example. im not sure i will keep all the raw touchstone files.
modified example
minor
added output of vnanoise analysis example
added another plot to noise analysis to illustrate the effects of averaging
added a passivity and changed copy import to deep copy, so it would copy objects of objects
added a multipath parametric standard. not sure if it will work or not
working on Network.passivity
added initial two port implementation
two port cal appears to work although new shit has come to light. i dont know if the s-parameters of the error networks can be uniquely determined.
fixed a bug i recently induced in workign band, which forgot to assign complex dtype to delay short. this did not get flagged in teh test cases. because i dont test all working band functions like delay_short.
trying to add two port cal, which is turning out to be time-consuming. teh calibration class's internal mechanism are a bit over-sophisticated and non-sensible.
two port apears to be working. need to make a coherent test case
minor
two port is working, fixed oneport2twoport function in network . starting to make paraterized standards twoport able
offset rectangular junction now supports returning a 2-port this should only be used when appropriate, ie when symetry holds
added parameterized standards for two port, such as line of unkown length, and waveguide thru,lines, with flange missalignment.
having a root choosing problem in one_port_2_two_port, which is showing up when calculating s21 from s11, as found by the variation methods for junction admittance.
made a hack-fix to the one port 2 two port function in network. im not sure how to justifiably fix this phase ambiguity. testing some new minimization routines, such as the gauss marquett (leastsq) and the fmin_slfp, whichi is iterative least squares with bounds.
removed all teh touchstone files in the example. it is too big and anoying
working workin
added and made some changes to the two port self-calibration algorithms. they are still being moved around. not sure if i want to implement the bounded parameters as i have
playing with self-calibration minimization algorithms, and bounding.
added interpolate function to network. needs to be tested
unsure of what i changed in these
fixed minor bug in variationalMethods, added a non-linear least squares solver for one port in the calibration algorithms
added a nonlinear least squares calibration for one port
added function to unterminate switch terms from two-port data
made the Network.plot_s_smith only draw smith chart if it doesnt exist this is tested by inspecting the number of patched on the axes
starting to add support for switch terms in calibration type.
added a legned_off function in convenience, not sure about the others
added dll folder for instruments

r400 , wow. got a pretty decent vna working. tested on 8720.
working on vna pythics instrument
pythics instrument tested on both 8720 and 8510C and simple functionality seems to be working.
added screenshot of pythics vna instrument
added a 'change_frequency' method to Network class, which does what you think. uses interpolation if frequencies are different lengths
changed smith chart labels
added a new module called programs which holds scripts and higher level programs which can be used from outside of the python shell
added a gnome mime definition for nautilus file manager integration also important note: i changed the way the network plotting commands default arguements so the default index is None and this will cyle through range of index.
changed the order which touchstone loads a file, so it raises a io error if file doesnt exist as opposed to a touchstone extension error.
added a socket futek class. it seems there is a strange problem with the subprocess class in windows, somthing related to the pipes.

made BIG CHANGES to Calibration class. and BROKE parametersized one port calibration type.
updated docs on calibration
added a one-port calibration example which illustrates usage of new calibration features
changed teh calibration algorithm for parametesrized cal to take keyword ideals instead of ideals_ps, for consistency with changes recently made to calibration class.
added a complex_components() function to return all usefule components of a complex number
changed frequency equality test to NOT consider frequency unit
updated the pydocs. changed the Network.write_touchstone() function to take dir and filname, like i used to have it. also i removed users ability to control extension, because its more anoying than usefule.
changed the touchstone class so that it will handle an arbitrary number of ports. i dont know why i didnt do this earlier.
found major bug in freespace, pertaining to lossy materials, which is why i didnt notice till now.
fixed another crucial bug in transmissionLine.functions electrical_length, for frequency units passed to gamma function
!!MAJOR CHANGES to transmission line functions !!
added conversion functions for distributed circuit parameters and wave quantities.
working on transmissionLine, and transmissionLineTest classes.
minor
changed variable names dramatically in tem class
working working
transmission line class is working pretty good now. tested against an hfss simulation of a cpw line.
started the n-port arbitrary connection algorithm. i am using the algorithm called, subnetwork-growth, and originated by Gunar Fillipson and also published by Rutledge and Compton.
finished n-port connection implementation. Has not been tested. Like the other s-parameter function this functionality was broken up into two parts: a S-matrix algorithm which can take either 'nxn' arrays or 'fxnxn' arrays, and then a wrapper function which takes mwavepy.Network types.
arbitrary connection of n-port network ports seems to be working.
implemented n-way lossless splitter.
cleaning stuff up, added a impedance mismatch standard to working band.
impedance step is working and some other network creation dependencies where made simpler.
updated docs and mistakenly added some pyc files. ill deleete them later
cleaned up working band, added ability to provide line lengths by electrical length. which is way better.
minor
implementing handling of port impedances
port impedance handling implemented for connect() function of networks. this is done my calculating the impedance_mismatch of the two ports and inserting this 2-port network between the two ports to be connected.
implemented port impedance handling for innerconnect function
added port impedance support to WorkingBand. havent tested much but appears to work.
started to convert docs to sphinx. eventually i will replace the wiki and manual with just the sphinx so i dont have to keep them in sync

starting the begining of a re-structuring of network creation. workingband and transmissionlines will be consolidated into a single class called media, or somthing similar.
fixed bug in interpolate, that i made when i fixed the z0 aspect of interpolate
added a new example for impedance matching to docs
working on new media class structure to replace workingband
added a tem class for TEM transmission line media
working
renamed tem to generic, which is more appropriate because it can handle tem as well as non-tem
working. this is a tricky thing to structure. there is no clean AND simple way to do it that i see.
added freespace Media class
added initial cpw class,
big commit. re-structure and writing of many media classes.
renamed and added new stuff
removed freeSpace.py should be freespace
minor
organized functions around in media, and moved transmissionLine.functions into seperate file, because the transmissionLine submodule is being removed.

working on test cases for media, and fixing bugs
massive changes. removed working band. removed all references to working band. where appropriate, changed to Media type,had to remove some parametric standards.
removed pyc files
BIG: removed workingBand.py
removed this dont need it
removing transmissionLine sub-module. it has been displaced by media.
trying to delete but svn is giving me trouble
fixed bug
removed discontinuities submodule, this relied on old transmissionLine class and is not very usefule anyway. needs to be re-implemented as special functions for media.RectangularWaveguide Class.
cleaning up
updated docs
creating a calibration sub-module and moving all relevent files into that
made an important structural change to Media Class. i needed to ability to pass propagation constant and characteristic_impedance as functions, so that calling them would cause their re-calculation. this is needed if properies of the Media instance changes.For example, if i change the frequency vector information, or a line-width for cpw, i want the propagation_constant and characteristic impendace to reflect those changes.

working on network docs
working on docs. im not sure what the standard on class property docstrings, i am including a Returns section so that the user can determine the type of the property.
working on docs
added dynamic subnetwork generated properties. super dank. next i am going to dynamically generate the rectangular plots
finished dynamic plotting methods for Network class. although i am not sure if i will keep this feature. the code is more concise and new plots are added with a trivial amount of work, but i dont know if the sphinx autosummary will work with dynamic functions.

Ralf Gommers (6):
BUG: make single stub matching example work. Also fix a few typos.
BUG: undo unintended addition of ':q'. Also whitespace fixes.
TST: make nosetests work. MediaTestCase shouldn't be a TestCase subclass.
MAINT: remove .pyc file that was checked in by accident.
MAINT: add .gitignore file, ignores .pyc and various temporary files.
TST: allow running tests with nosetests also when not in testCases dir.
SjoerdOptLand (1):
quick fix in case no Frequency instance is passed to Calibration()
