TrueTime Symmetricom XL-DC 86-357-24 Quad 10MHz Card Low Phase Noise BNC Output [Refurbished]

TrueTime XL-DC 86-357-24 Low Phase Noise 10MHz Option Card Used, Very Good Condition Removed from a working XL-DC chassis with an OCXO or Rubidium oscillator installed. All outputs were checked for a good 10MHz signal using a frequency counter - see below. I cannot guarantee that this card will work in receivers other than the XL-DC (OCXO or Rubidium) type. This is a multiple item listing so there will me minor, non-performance affecting cosmetic variations 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 XL-DC system, such as an OCXO, High Stability OCXO, Rubidium or High Stability Rubidium. SPECIFICATIONS: LOW PHASE NOISE 10 MHz OUTPU
