Kaiser,
I don’t think the GPIO sweep switching is going to be adequate for your task since you are doing the 100MHz spans. It was originally designed to antenna switch over multiple GHz sweeps. It only operates at the granularity of the LO step freq which is 160MHz in your case, or 40MHz in the slower sweeps.
The I/Q GPIO switching you saw does not work in sweep mode.
Thinking about what we could add to the API, what if the API gave you the ability to queue GPIO switches in between sweeps. For instance, insert a single GPIO switch in between StartSweeps? Do you think this would be adequate for your measurements?
I don’t think it would slow down the sweep speed at all.
Given the 100MHz span, I think you would have to give up sweep speed to accomplish what you need with our current API.
If you think the proposed solution would work, I can potentially look into adding this for a future update? You could simulate this by calling
smGetSweep() -> smSetGPIOState() -> etc..
albeit at a slower sweep speed.
Regards,
Andrew
