Tom, The P3 can monitor the K3 IF spectrum right now. A spectral display is often more meaningful than an envelope display on an oscilloscope. For instance, it may be hard to determine just when the waveshape of the envelope begins to flatten, with a spectral display, it is easy to see when spikes appear that are other than the tones themselves. I would rely on a spectrum display more than a 'scope display for 2 tone testing.
Yes, it is not monitoring the actual transmit frequency, but the IF signal. One could use a tap on the transmission line as well as attenuators to bring the output signal down to the point where it could be sampled by the P3 - the P3 input frequency can be changed to most anywhere in the RF Spectrum. 73, Don W3FPR On 11/5/2011 1:13 PM, [email protected] wrote: > All, > > By using the Config:2TONE function, one can tune USB or LSB output using a > scope.
