WfmBuilder

GUI based Python program to send custom waveforms to a Agilent/Keysight 33600B

Example

Getting Started

Initial instructions:

Prerequisites

  • Python 2.7
  • pyvisa
  • matplotlib
  • numpy
  • PyQt4
  • pyqtgraph (beyond v3.0)

Installing

I suggest downloading WinPython as it will install many prerequisites. Use pip to install other preq's. Download .zip file or clone from GitHub url into local directory.

Operation

  • When GUI opens, it will scan for local GPIB, USB, etc. connections.
  • Select your intrument address from this list to connections
  • Hit "reset" button to reset instrument.
  • In the main window, you can now build a waveform using strings

Defining waveform 1) Alt. ramp, delay

  • Define waveform functions separated by space
  • Begin with 2 string qualifier, followed by variable number of csv inputs to be interpreted as floats:
dl1e05 #delay in seconds
rm45e6 #ramp in V/s slope
er1e4,0.05 #exponential ramp with time constant in s, and total time of section
cs5e6,1,0.5  #cosine builder, set period in Hz, start phase/pi, end phase/pi (1,2 = valley to valley)

Defining waveform 2) Amp. step

  • Then define amplitude step for each waveform
0 1 2 1
  • This will turn boxes black, indicating you should hit 'enter' when selected to upload to the insturment. Instrument will turn off when uploading waveform, then go to the previous state.

Other options

  • Can change output load, sample rate, offset voltage, and of course turn it on/off.

Versioning

I use SemVer for versioning. For the versions available, see the tags on this repository.
