The highest frequency I can generate is 2.5 GHz. My counter can measure 20 GHz,
to 1 HZ. At the moment I'm have a frequency locking problem with the extension
module in my HP 8660C, so I can't even get to 2.5 GHz, only 110 MHz at the
moment. I gust got some extender boards, so I hope to have it fixed soon. The
X72 gives me a solid 10.000000 MHz, I would like to see what I get when I use
the Rb as a clock for the signal generator, at 2.5 GHz. I guess I only need to
verify the calibration with the GPSDO, when I get it, and get it working. Then
I can calibrate everything else.
So, to make a long answer short, I don't think I need the level of accuracy
that these devices are capable of. I just have a neurotic need to try and make
things as exact as I possibly can. Also, this is just a hobby, and learning
experience for me, so I can take my time to work things out.Thank you,Steve

Even an undisciplined rubidium oscillator is going to be very close to
nominal 10MHz. You have never stated your desired precision that I have
seen. The X72 manual says that the output should be within 1E-9 in under
10 minutes, and within 5E-11 after 30 minutes. Does any of the equipment
you use have finer precision than that?
