Hi Kaiser,
You are correct to note that sweeps are not synchronized between devices. There are unknown latencies that exist such as USB timings/etc. We don’t have any mechanisms for synchronizing sweeps for our devices currently.
The traditional way to synchronize measurements for our devices is with the trigger input port in IQ acquisition mode. Aligning the spectrum measurement (FFT) on the IQ data after detecting an input trigger on each BB60C is the way to accomplish this type of task. As you correctly noted, the bandwidth would be limited to 27MHz at that point.
If you are measuring a pulsed signal and depending on your measurement, you may not even need an external trigger, you could simply look for a video trigger (specific amplitude level in the IQ data) and align on that.
While it doesn’t help your current situation, we are investigating a 160MHz IQ BW triggered acquisition for the SM200A.
We don’t have immediate plans to look into a triggered sweep measurement for the BB60C, but we do appreciate you sharing your use case. This can help us guide future development.
Regards
