I own several spectrum analyzers and build various RF boards at all kinds of frequencies.
I was looking over a BLE FCC test report for emissions, and I saw this lab uses a RF power meter to measure the output of the system.
Why would you not use a spectrum analyzer for this?
Why does an RF Power meter even exist? Is it simply because it is cheaper than the spectrum analyzer?
Can anyone weigh on the rationale for an RF power meter?
I'm looking at this very expensive looking RF power meter, and it seems like just a spectrum analyzer that sweeps over frequenicies:
I understand the smaller handheld RF power meters probably just take average readings of power without the frequency sweeping?
