I've used the XG3 as signal source for testing/aligning VHF to mw
gear and do not worry about its accuracy/stability. Instead I use my
EIP538 counter which is good to 26.5 GHz using either the internal
TCXO or my Rb source into the counter reference port. At turn-on the
XG3 drifts quite a bit but after 20-min or so is slow enough for
aligning Rx front ends. I have some heated xtal signal sources that
act the same way but operate at mw frequencies.
Its a fine piece of test equipment for its size/cost and generates
useful signals up to 1296-MHz. Above 200-MHz the output level is
uncalibrated as you are using a harmonic of the output which will be
lower level. So not real accurate for testing receiver MDS, still it
can make a ballpark test of a receiver (is it good, mediocre, or
bad). For HF thru 2m quite good for measurements.
If you do not have a counter its harder to check its frequency. Good
suggestions have already been made. EIP538 is one of the best $500
investments I've made. HP141T is another.
