LeCroyScopeDAQ

Command line DAQ for LeCroy X-Stream oscilloscopes.

Written by W. H. Bell [ http://www.whbell.net/ ]

Description

The oscilloscope parameters are set from the values given in the control/settings.txt file. The scope is then setup and readout for a given number of triggers. The data taken from the scope are decoded and recorded in a Root TTree saved in a ROOT file.

---

Building the code

cd src
make
cd ..

By default, the code requires ROOT [ http://root.cern.ch/ ] to build. However, this dependency can be removed by removing RootTreeOutput from the OBJECTS= list in the src/Makefile .

More details on the structure of the code are given in the src/README.txt file.

Setup the scope parameters

The oscilloscope settings are controlled by the text file

control/settings.txt

where each parameter name is given followed by at least one space or tab, and then the value for the parameter.

Running the code

./bin/scopeDAQ.exe [options]

where [options] is optional and can be:

• -h to print the possible options
• -d to enable the debug mode, to print more information
• -m to set the run mode, where can be 0, 1, or 2.
• -n to set the executable to read a fixed number of events
• -o to set the output file name prefix
• -p to override the default control/settings.txt parameters file name

Run modes:

• 0 - read oscilloscope traces, decode them and write the data as a ROOT TTree.
• 1 - read oscilloscope traces and write them in the binary data format
• 2 - read the binary data format and write out a ROOT TTree. In this mode the data is read from the input files, rather than from the oscilloscope.
