Thank you for the reply.? The probe is a PP-150 which came with the oscilloscope.? I have used it for a few years.
Its bandwidth (@10:1) is 100 MHz.? The probe compensation allows the square wave calibrator to show a good squarewave with no ringing.
The input impedance is 10Mohm/18.5pF.
It is the output voltages from the ExOR gates and the AND gates that concerns me as the lower the voltage output, the lower the RF output from the BS170's.? The measured RF output is within a few 10ths of a Watt as shown on the puTTY Terminal.? Both measurements decrease at the same rate to 0 @ 6m.
Any help you can give would be appreciated.
Regards
Greg
