Measuring Power Precisely and Quickly for AC Current/Voltage – High Frequency Low Power

I am looking for a way to measure the power into or out of RF mixer circuit. And others...I would like to find a way to do this quickly and efficiently, and as precisely as possible and am curious what the EE community has to say. I will buy equipment if necessary if there is something that does this within our specifications.Frequency is 30MHz-40MHz. Pulsatile. On for Xus and off for Xus but I would like to find a way to measure the power through components during each state or overall, through each state. This is clearly not a sin wave, not consistent, but the pattern is repeatable.  It is tough to measure power in these situations. But it is necessary. Max power is -6.5dB. (or is supposed to be). Max input/output voltage of the mixer is 1.2V P-P.I appreciate any support and feedback, or ideas of how to get all dynamics of power measurement in this situation as affectively as possible.

HelloYou can use a load probe as shown in the figure. If the signal is very low, then it is better to amplify the signal with a very fast OPAMP, and insert the output signal to the probe.RegardsGiovanni

A few questions,  is the mixer a commercial product, or roll your own. Is it being used in a receiver or a transmitter. Is it being tested standalone, or is it embedded in a system.In theory, a basic scope will do what you want, but operating a mixer near its limits will introduce an increasing number of harmonic responses, any  maximum ratings  should specify what some of these are,  the level of compression, for example. Are the maximum ratings related to signal performance, or to damage of active devices? Operating a mixer near its limit may mean that a spectrum analyser is necessary if you are to avoid problems, and it may be highly desirable anyway, particularly if it is your own design.Incidentally, -6.5dB is meaningless, this is a relative value, are you sure you don't mean dBm?Cheers,Richard
