Hi Bittware,
I don’t have a timeframe for when SCPI support for zero-span would occur. I’m assuming triggering is an important aspect of your measurement? If so, then using the API directly to request IQ, trigger, and then FFT the IQ data to create the spectrum plot is the only alternative. Otherwise if you do not need triggering, then using SCPI with standard sweep mode seems like it would be adequate.
If you haven’t seen the APIs yet, you can find them on the SDK landing page.
