Symmetricom 87-8009-10 XLi Low Phase Noise 10MHz Quad BNC Output Card Microsemi [Used]

Low Phase Noise 10MHz Option Card • Four 10MHz Outputs on BNC Jacks • For XLi Chassis • Part Number 87-8009-10 • Used, Good Condition

Used and in good condition.  Removed from a working XLi chassis where all outputs were checked for a good 10MHz signal using a frequency counter.  This is a multiple item listing so there will be very small non-performance affecting cosmetic differences between units.

Description

This card provides four isolated, 50 ohm 10MHz frequency output signals with exceptional spectral purity. Isolation from the receiver’s internal digital signal noise and power supply noise enables high-performance phase noise and spurious noise characteristics as the on-module low noise oscillator source. The low phase noise option requires an oscillator upgrade to the XLi/XLi SAASM system, such as an OCXO, High Stability OCXO, Rubidium or High Stability Rubidium.
