Hi Booth,
I have tried the 10MHz out from a MXA N9020 Signal analyzer and the PN seems not to improve much.
I’ve bought a used ISOTEMP OCXO82-108 from AliExpress and I will test it after arriving.
Since the internal VCTCXO RPT7050A has very good PN performance (-130dBc/Hz@100Hz), I don’t think an ext. OCXO will improve much.
Thanks for helping:)
