LabView for SCT128A
Version 2.0 6/12/00
Version 2.1 8/5/01
Bug fixed for 40MHz gated sirocco strobing.
Requires LabView V5.0 or later
I recommend a fast PC. I use a 450MHz PIII machine with 128MB RAM, which
event rate of ~20Hz with full event analysis and real-time histogramming.
National Instruments VME-MXI-2 interface
Corbo (CES RCB 8047)
Sirocco - both old and new 40MHz sirocco
TDC - CAEN V488A
The software package comprises 4 programs:
You can view some pictures of these vi's by clicking here.
runDAQ.vi - full DAQ system, with file management, full event analysis
and histogramming etc.
readData.vi - "playback" of raw data files, with event-by-event analysis
readHistos.vi - view and analyse saved histograms
sct128Tool.vi - interactive facility to set up and trigger the chip, ideal
for debugging, observing
the data train, setting up strobes etc
Download each of the four llb files:
- this will include runDAQ.vi
- this will include readData.vi
- this will include readHistos.vi
- this will include sct128Tool.vi
You also need to create two files, and a few directories:
Then set up the VXI configuration, so that the hardware has the following
a DAQ configuration file, which defines directory names etc for data storage
etc. Download daqconfig.txt
to start with, this is the configuration file I use at Cambridge.
Then save it as C:\sct128\daqconfig.txt. Look in the file, and manually
create the 4 directories listed in it.
a hardware configuration file, which defines the default chip settings,
the choice of sirocco, whether
TDC is read out etc. Download default.txt
to start with, these are the current settings I use at Cambridge. You can
later change the hardware configuration file from runDAQ.vi.
You must save the default.txt file in the directory 'directory for hardware
configuration files' listed in
If you want to have different VISA Resource names, edit the file GetVXIMap.vi
and edit the CASE structure
