The TCXO runs on 30MHz and the lower cal output frequencies are created using a divider instead of a PLL
The cal output is like to 10MHz reference clock of other spectrum analyzers.
If the cal output is offset you can correct it using the CONFIG/EXPERT CONFIG/MORE/CORRECT FREQUENCY where you can enter the actual frequency of the 10MHz cal output

Erik,
I measure my 30 MHz. cal output and it was 45 Hertz off.? So I measured the 10 MHz. cal output and it was 15 Hz. off.? I went to CONFIG/EXPERT CONFIG/MORE/CORRECT FREQUENCY and entered 9999.985 K and did not notice any difference in the 10 MHz. cal output.? So I thought maybe this is just a divide by 3 of the TCXO and this offset adjustment does not have an effect.? So I went to the Low Output mode and? set it to 10 MHz. and i was still 15 Hz. off.
Could you please provide further details on how to use this feature or point me to a video that explains proper procedure.?
