Wow mate cool it mate you're drilling me man.
As I said, excuse my intemperate outburst, but as someone who is new to the forum you will not know that we have had a couple of trolls who ask nebulous questions and when asked for a bit more information all they do is trot out the same words and do not give any more information on which to base a meaningfull reply.
OK, trying to get a bit more positive and helpful...
The first most obvious thing to measure about an RF signal is the frequency.
For most practical RF frequencies (up to a few GHz), this is done with a frequency counter.
Counters which can work up to several 10s of MHz are easily made using a PIC.
The frequency range can be extended up to several GHz using a pre-scaler.
RF power can be measured using a variety of techniques, low powers are paradoxically harder to measure than high powers.
It is also useful to know the spectral purity of a transmitted signal to ensure that you are not vomiting RF noise all over your RF neighbours.
To do this a spectrum analyser is used. Generally speaking this is where you can spend lots of £££ $$$ €€€.
However, is possible to get good cheap spectrum analyser features using an "SDR Dongle".
To test a receiver, you will need a signal generator.
To get a well performing one it is necessary to spend lots of £££ $$$ €€€.
But as already suggested, the best (easiest, cheapest and legal) way for someone with no RF experience is to use the readily available modules.
