Hi Andrew,
Thanks for the advice.
Based on your description, I’ve given up the SA44B.
Zero-span mode has little help to my application, as it only provides meaningful info. in time domain whereas my interest is the central frequency drifting performance of the carrier.
Let’s focus on the BB60C in real-time mode, I still have following concerns:
1. What is the IF sampling rate of BB60C?
2. Could you elaborate on “1.25 FFTs worth of data”? I guess it means 1.25 times the min. point of FFT which is (?) Would you do multiple overlapped FFTs within the same sweep time window?
3. When you mentioned “We accumulate ~30ms worth of spectrum before displaying the results in real-time which means you will see the accumulation of several pulses in your config in one sweep. ” I guess capturing multiple pulses within the same sweep time window is a good thing. Two seperate 5uS pulses is equivalent to one consecutive 10uS in terms of spectrum resolution providing the two pulses have the identical spectrum content. Am I correct?
Looking forward to your feedback.
Thanks a lot.
Best Regards,
