Symmetricom TrueTime 87-8022 XLi Triax N1 Frequency Synthesiser Output Card N.1 [Used]

Here's a used quad frequency output option card removed from an working XLi GPS clock/frequency generator. I can't guarantee that it is compatible with clocks other than the XLi type. Note that the connectors are Triax type and not BNCs.

Description - N.1 Frequency Synthesizer (87-8022)

The N.1 Frequency Synthesizer card’s four independently programmable outputs generate frequencies from 1 PPS to 50 MPPS, with a tuning resolution of 1 PPS.

The N.1 module outputs are independently frequency locked to the XLi's internal oscillator. Therefore the N.1 outputs have the same frequency accuracy and long term stability of the XLi's internal oscillator.

The N.1 Frequency Synthesizer is configured from the front panel keypad and command line interface using F120 - N.1 Frequency Synthesizer (see Manual Page 158). It can also be managed using the web interface.
