mw power measure
I didn't see any phase reading for spectrum analyzer.
Thanks.
Some VNAs (Vector Network Analyzer) are able to display the level in dBm other than dB. Depend on VNA model.
Phase. For the phase the concept is different. Knowing Phase, make sense only if you have a iso-frequency "reference". A "Reference" require at least a comparition or normalizzation wich is the simplest type of calibration. But if you calibrate the VNA, you'll get only relative measurement, not absolute power.
So: to get Absolute Level and Phase you should perform 2 different measurement:
1) Read Power level (Uncalibrated VNA)
2) Read Phase (Calibrated VNA and 1 port connected to a Ref Phase Signal)
Thanks a lot!
My VNA is 8510C, could you suggest how to perform a phase calibration?
thanks a again.
