* Item Description
Symmetricom X72 is a compact 10 MHz rubidium oscillator frequency reference standard similar to the SA.22c and also supports a serial interface like the more sophisticated SRS PRS-10.
Case is clean and prepared for a new thermal pad. Requires 10-32V power supply, heatsink and Symmetricom or BG7TBL interface board.
Unit can be disciplined with a 3.3V PPS timepulse like the Leo Bodnar LB-1421.
Calibrated July 2025. 18-hour bench test shows ADEV 4.05E-12 and Δf/f +1.52E-10 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.
