Hi all. Currently we have to measure power variations at about 8 GHz bandwidth (at the GHz range). The thing is we have to measure that with a 100 MHz resolution, given the IF bandwidth of the pna is at max 40 KHz.

We were thinking on simply average manually several points(e.g., use 40khz IF bandwidth, and average every 2500 measures). Given the pna measures up to 32k measures and the 8 GHz range we want to measure, it wouldn't be enough this way (but we can measure in a smaller range, e.g. every 2 GHz).

My question would be, it's the above idea ok? And just in case, there´s another way to make that measurement?

Thanks in advance

On the other hand, you might consider the PNA-X as it has a 5 MHz IF BW and it has a direct "channel power" measurement function in the latest equation editor example that is just what you probably need.
