Hi Julian,
As possibly the person who is the culprit of the list of features AJ now has on his to-do list, here’s how I used my SA44B (oh for a BB60C!).
You can get around QP by using both Peak and Average. QP is proportional to signal duty/waveforms/etc so will always be bracketed by either Pk or Avg.
More important is the RBW, as this needs to be the same or close to that defined in the appropriate standard. I just left everything set to 9kHz.
I found the most useful feature for EMC debugging is the demodulation to audio for signal identification. Especially when in real-time mode.
For EMC debug you dont necessarily need calibrated antennas as you are looking for relative changes. However most RF compliance labs will charge to calibrate and to provide antenna factors vs frequencies.
Precompliance is slightly different as its typically the first test so you wont have a benchmark. Again, a local lab may be able to rent to you a calibrated antenna (with factor table) or calibrate your antenna against a known standard.
By way of an example, I have made a whole bunch of near-field probes, made a couple of PCB-based log periodic antennas and have almost finished an open TEM cell.
You might want to have a read of my other posts (on the Spike sub-forum) about feature requests. They all stemmed from an EMC debugging exercise.
Which, I have just been informed, now passes.
Rgds,
Jared
