Very Nice and a lot cheaper and more portable than most signal
generators. 432.66 is third harmonic of 144.22 and 9th harmonic
falls on 1297.98 (a little high for 1296 but may be usable). But if
the frequency can be moved by computer control, then very useful. I
like that it will go down to -107 dBm (my 2m eme threshold is -152
dBm*). The harmonic energy should be 1/n in level if true to most
devices like a diode. 50ppm implies 144.22 x 50 Hz = 7211 or about 7
KHz at 2m.
*Note: I have two 20-dB and one 30-dB step attenuator so I may be
able to reduce the level for testing at -150 dBm.
The 0dBm level may be strong enough for use with a rotating dipole
for calibrating my 2m-eme dual-polarity receiver channels (about 130
feet of space loss). I have signal sources for 1296, 1420, and 2401
MHz that runs approx. 0 dBm and are detectable over that range.
Very nice tool, Wayne. Guess I will have to get one.
