Quantum Composer Pulse generator 9518+ control via Labview

[lukasra]

Hello!

I am trying to implement my own labview program to control my pulse generator from QC. As a first step I try to use the example program written by QC. However, I get an error as follows:

Error -1073807339 occurred at VISA Read in Quantum Composers 9000 Series.lvlib:Utility Write to Instrument.vi->Quantum Composers 9000 Series.lvlib:Initialize.vi->Quantum Composers 9000 Series Initiate Pulses.vi

Possible reason(s):

VISA: (Hex 0xBFFF0015) Timeout expired before operation completed.

It seems like the problem occurs in the write function within the initialize vi. I have tried to increase the timeout, but it does not seem to help.

Very grateful for all help!

Best,

Lukas

I believe you're using the example,

Few things to troubleshoot

1. Check the 'VISA Resource' name specified in the VI
2. Make sure the cabling between the instrument and the system is proper
3. Based on the communication method, verify the settings in NI MAX (for GPIB, like termination character etc.,)
