AES.Org AES11-2003 paper say AES Grade1 Clock is 1ppm,
any TCXO or OCXO Xtal has <1ppm at 31°C with clean & stable power.
Rubidium Atomic Clocks have parts per billion +-0.03ppb.
acording to Teac Esoteric and Antelope 10M specs.
....
tested 2x times the M-Clock, and the diference between M-Clock tests were less than the RME Clock diference.
you can see in the screen shots:
M-Clock +4dBu,
M-Clock -16dBu.
two diferent tests with same clock.
The M-Clock was not calibrated in those tests, had drift.
recently did a re-calibration to factory specs.
