Symmetricom TrueTime 86-8008 XLi Quad Sine Square Wave Frequency Output Card GPS [Used]

Here's a used frequency output option card removed from an XLi GPS clock/frequency generator. Each channel can be set to a different sine or square wave output value by means of a jumper on the board. All outputs were tested before the card was removed. I can't guarantee that it is compatible with clocks other than the XLi type, although I suspect that it works also in the XL-DC chassis (as it doesn't communicate with the receiver's CPU).

Description

The 1, 5, 10 MHz/MPPS card generates four stable-frequency sine or square wave outputs through its four BNC connectors. These outputs are phased-locked to the XLi’s disciplined internal oscillator or external frequency reference source.

The card’s output frequencies are set by manually configuring jumpers on the output card. Once configured, they are automatically enabled upon power-up. No additional hardware or software configuration or set up is required.
