Hello to all Network Analyzer Guru,

Hope you are having wonderful Monday morning.

I have simple question about PNA-X power measurement.

When i make power measurement using PNA-X, (after source and receiver cal) I see about 0.15-0.2dB compare to result i have with 8480 series power sensor.

I was wondering what could create that difference. (DUT: high power (~150w) amplifier)

Thank you in advance.
