Enhanced Low Phase Noise 10MHz Option Card • Four 10MHz Outputs on BNC Jacks • For XLi Chassis • Part Number 87-8040 • Used, Very Good Condition
Removed from a working XLi chassis where all outputs were checked for a good 10MHz signal using a frequency counter.
Description: ENHANCED LOW PHASE NOISE 10 MHZ OUTPUT
This module provides the lowest phase noise frequency outputs from the XLi. Four isolated, 10 MHz frequency output signals with exceptional spectral purity. Isolation from the receiver’s internal digital signal noise and power supply noise enables the high-performance phase noise and spurious noise characteristics that approaches the performance of the on-module enhanced low noise oscillator. This option requires an oscillator upgrade to the XLi system, such as an OCXO, High Stability OCXO, Rubidium or High Stability Rubidium.
