Reply To: BB60c with 10MHz external reference from TG44 shows me large frequency deviation

[Ivan Ionov]

I’ve checked TG44 output against its 10MHz ref ouput on oscilloscope.
When I set tg44 output to 10MHz or 20MHz, it generates sine phase locked with reference (frequencies matches exactly). But 30MHz, 50MHz, 100MHz are not in phase and have some frequency deviation. For example, to generate exact 10x phase locked output I have to set tg44 freq=99.999970MHz

As I understand, instead of tuning internal tg44 reference generator to exact 10MHz, you simply set some freq correction parameter into it. This makes useless it’s 10MHz output.
