Good Day,
I have built a radio telescope and I am currently reading the changing voltage across the satellite meter in millivolts. I can produce a very nice drift scan of the Sun. Professional radio telescope receivers use a square law device in the detector. I am using a simple Channel Master satellite meter and a digital multi-meter to read the signals from a dish with LNB. Does my digital multi-meter have a square law device? Is the d-c output voltage proportional to the input-voltage amplitude squared? Or is the square law device on the Channel master board and I am simply reading the output with my multimeter?
Thanks,
Henry
