I am using a PNA-X, N5242 to make some absolute power measurements.
Someone in my department told me that the reading of the absolute power will be the peak power, but I wanted to double check to make sure this correct.
Also, it seem that the raw data that I grab from the analyzer, using COM, seems to be relative to 1 mW. Is this also correct?
Thanks,
Chris

If you grab the formatted data, and the format is logmag, then the data will be in dBm (dB relative to 1 mW). If you grab the unformatted data, then it will be in the units of sqrt of power relative to 1 mw, with real and imaginary terms where the power needs to be computed as real squared plus imag squared. I would recommend to always get formatted data to know that the units are either in Watts (linear) or dBm (logmag).
