That is debatable.
Not if you study the data sheets and specs for both.
The LP100A can read complex impedance at the point of measurement on the
line, so it could be used to find the input Z of a power amp (using a
Smith Chart to account for line length from the coupler to the amp). It
The unit is factory-calibrated to NIST, power accuracy is 5% worst case,
3% typical, at any signal level from 1W to rated power. It can read peak
hold, average, and instantaneous peaks. It can auto-switch between two
couplers on the outputs of my SO2R contesting station.
