A used Trak 8821 GPS Disciplined Clock/Frequency/Pulse Generator with a 10MHz OCXO oscillator installed. The unit has been tested and found to work as expected with the correct date and time shown via the IRIG-B timecode output. The responses to the various control commands are copied below. This seems to be a later revision than referenced in the manual linked below as it has a later 12 channel Motorola M12+ receiver installed. A basic puck antenna is included to allow you to test the unit immediately upon receipt. For a permanent installation and accurate time/frequency generation a professional grade outdoor antenna with a clear view of the sky will be required (TNC rear panel connector). I can provide a recommendation if required - the antenna voltage is 5V so almost any professional grade outdoor antenna can be used. Full product information may be obtained from the User Manual (a close match) at https://www.prostudioconnection.net/2111/Trak_8821A_Manual.pdf.

Description

The Model 8821 GPS Clock incorporates a multi-channel parallel GPS receiver, a disciplined crystal oscillator, and a precise time and frequency generator in a single cost effective assembly. Phase offset of the 1 PPS output, referenced to UTC, is typically less than 100 nanoseconds when one or more satellites are being tracked.

The Model 8821 incorporates automatic oscillator calibration by GPS, automatic leap second correction and built-in calendar for automatic leap year updates. By using the remote setup feature, the operator may set up for automatic daylight savings time corrections. These features, plus a very high MTBF, and an RS-232 remote status-monitoring feature virtually eliminate the need for site visits for setup, calibration, and maintenance.
