How accurate? What frequency range? What spectral performance (harmonics, spurs)?
One thing to watch out for on testing with very low level signals is leakage out of the signal generator and into the unit under test via a path other than the coax. When we test deep space transponders at work at very low levels (-160dBm), we actually use a signal generator at a different frequency and multiply it up externally (partly that's also because historically, the signal generator didn't go high enough (7.15 GHz).. But when you use a modern signal gen that does work at 7GHz, you've got to be more careful). .. In any event, it doesn't take much to turn your careful and precise -160 into -159 or -161.

I have received great advice in the past with items for my little shop and I can't resist to ask again. I am thinking about buying a signal generator. I suspect that I will mostly use it to inject low uV/mV signals into the amplification stages of the laboratory instruments I service. Any feedback you have would be greatly appreciated-Patrick _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
