Thank you.
I redid the tests, with a GPSDO (output set to 100MHZ)
In this test, SA124B showed smaller offset/difference:
SA124B -0.1Hz (BB60D: 34Hz)
I also played with the Sweep Recorder. If I understand correctly, upon Playback, I can only check the spectrum and read the power by Marker, as other parts in menu are greyed out in the playback mode (e.g. the Analog Demod or Freq diff meter), but then as you explained, that won’t be an accurate method to check frequency reading accuracy/stability. Do you know what I can do for this?
Also, FYI I am only curious to test the SA124B’s stability over time and compare it against BB60D for experimentation, otherwise, as you mentioned, I will use an external reference for more accuracy/stability in my real world measurements.
