It occurred to me that the P3 might be made into a decent 200KHz wide RF
spectrum analyzer (note analyzer, not display) with the addition of N
trace averaging (n, infinite).
I use my K3 as test gear as well as for operating. With an elementary
sweep generator, K3/ROCKY almost works as an RF spectrum analyzer if it
only ROCKY could average sweeps.
SPECTROGRAM/Sweep generator does work fine if you're interested in AF
stuff. SPECTROGRAM has a user settable integration time. Compared to a
noise generator, one can pick up another 20db of "skirts" with a clean
swept signal. I've found sweeping in the range of 1-10 seconds over
sizable chunks of spectrum quite practical. Integration times of 10-100
seconds could produce quite very useable display. Substitute SPECTRUM
LAB for SPECTROGRAM and things really get interesting. One can dump of
the Fourier Transform bin data in sub-Hz intervals if you want for plot
comparisons or math manipulation.
Since the P3's IF can be set to anything between 455KHz to about 30 MHz,
one wouldn't need the K3. Just a test jig, sweep generator and P3.
Sweep generator signals are way more than adequate to drive the P3.
Goofy idea?
No. I don't have a P3 presently.
