| #18: Use Oscilloscope with delayed time base to measure a RF Power detector This video shows how I used a scope and a signal generator to perform a quick check on the proper behavior of a broadband RF Power Detector that I recently picked up at a hamfest. The signal generator is setup to produce a pulsed RF signal, and the scope is used to look at both the RF signal as well as the RF detector output signal. The delayed timebase feature of the scope is used to zoom into the rising and falling edges of the RF pulse so that the response speed of the detector can be observed. It is also shown that for this type of detector, the response is a strong function of the load presented at the detector output. https://youtu.be/vvqVTD-VEow |
