GPIB data acquisition with tetronix TDS 210 oscilloscope needs to change to LeCroy wavejet 324 oscilloscope

[hotha]

Hi,

I was using Tetronix TDS210 oscilloscope to squire data. But I need to change the oscilloscope to LeCroy Wavejet 324 now. The program is not even reading the signal now. What are the things I need to change?

Thank you

You likely need to go through all of the SCPI commands and make sure they are the same.  Another option is to look in NI's Driver site for the LeCroy scope and use those drivers instead.

Quite frankly, I would suggest a complete rewrite. You are using stacked sequence structures, GPIB functions instead of VISA, a lot of local variables, hidden wires and structures, as just a start. You should know that the command set varies from vendor to vendor and often from instrument to instrument. If you had used the instrument driver for the tek scope, you could have perhaps had an easier time to replace common functions. As it is, if you want to use the existing code, you will have to replace each one of your hard coded GPIB writes with the appropriate write for the LeCroy.

As a side note, this is the sort of situation where IVI drivers would have made a big difference. If IVI drivers exist for both instruments and if you have used the class drivers, you would not have had to change anything.

We have a project-style driver for the Wavejet Series and will be releasing the IVI driver soon possibly in the next month or early March.
