Hi all,
I'm trying to measure the power of an rf signal that frequency ramps over 200-400 MHz. My signal strength as measured on a spectrum analyser is around 0 dBm (into 50 Ohms) post-amplification (expects 50 Ohm load), but I'd like to know the total power in this band without requiring the analyser. Ideally I'd be able to measure Vrms or an associated quantity.
Naively I considered rectifying the signal and charging a capacitor, but given the high frequency and (relatively) low amplitude of the signal I'm not sure this would work. Is there any "obvious" solution to this besides purchasing test equipment?
Cheers
