Can non-NI IVI driver calls be debugged using NI SPY?

[Anbu]

Hi,

I would like to know whether NI-Spy supports only NI specific driver calls or its scope is extended to non-NI but IVI compliant drivers.

Also if any custom driver is developed using lab windows then will NI Spy support debugging of these custom APIs?

Regards,

Anbu

Hi Anbu,
NI-Spy only supports NI specific driver calls.  You can see the supported drivers by going to:

NI-Spy -> Spy -> Options -> View Selection

If your IVI driver uses VISA library for instrument I/O, and your runtime (debug) environment installs NI-VISA, the instrument I/O processing on the NI-VISA call can be captured by NI-SPY.  For example, IVI-COM drivers made by Agilent also use VISA library therefore they can be captured by NI-SPY if the runtime environment is NI-VISA.
