Normally we measure power of high frequency signal using power sensor which convert the power of signal to power around its DC component then monitored by power meters .
Now , is it valid if we use the system of current probe +digital scope +power module?
Hello Ali,
I think, it is best to get the calibration done for whatever method you adopt and then validate your test results.
When you are involving many individual instruments - as your case is - current probe+ digital scope + power module, you will need to calibrate or atleast provide traceability to some standards for all the instruments.
I do not know what power level you are working with but there are some specialized chips available that can be used for RF power monitoring purposes. I am currently using AD8307 from Analog Devices for
