I've seen lots of posts regarding measuring output power. The technique I've used for years is simple and effective, all it requires is an oscilloscope. It doesn't have to be a top of the range high frequency instrument either, provided the DC scale is reasonably accurate virtually any scope will do, all that is required is to build a very simple diode probe and use a calculator to work out what the power is across a 50 Ohm load.
Have a look at this site from Adam Farson, VA7OJ/AB4OJ, Fig 3 shows the simple diode probe connected to a digital multimeter (DMM), in place of the DMM use the scope. http://www.ab4oj.com/pwrmeas.html If you are measuring higher power levels use the 10:1 attenuator as in Fig 2. Just speak into the mic and watch the peaks, it's far more accurate than any meter can possibly be and far cheaper, there are plenty of surplus scopes for sale. Once you've used an oscilloscope you wonder how on earth you managed without one ;-) 73 Paul G4LNA. -- View this message in context: http://www.nabble.com/Power-output-measurement-tp17165068p17165068.html Sent from the Elecraft mailing list archive at Nabble.com. _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
