SA.22c Rubidium Standard | 10 MHz
Symmetricom SA.22C is a compact 10 MHz rubidium oscillator frequency reference standard supporting a serial interface like the more sophisticated SRS PRS-10.
Requires 15V 1.3A power supply.
SA.22c also accepts 5V power and can be disciplined with a 3.3V PPS timepulse like the Leo Bodnar LB-1421.
Calibrated January 2026. 12-hour bench test for serial 7569 shows standard is performant with ADEV 1.08E-12 and Δf/f -1.13E-11 for τ 10,000 s and average time 30,000 s.
Performance of a rubidium standard deteriorates after decades and many on eBay are well over twenty years old. While an older unit may still be performant, you cannot tell unless its frequency stability is verified.
