5.7 1 PPS OUT BNC (-GPS, -IRIG)
The 1 PPS output is a 200 ms wide pulse (rising edge on-time), generated by the TYMSERVE
and synchronized to the timing source.
5.8 FREQ OUT BNC (-GPS, -IRIG)
The frequency output signal is a TTL output set to either 1, 5, or 10 MHz. This output is
synchronized to the timing source.
5.9 PERIODIC OUT BNC (-GPS, -IRIG)
The periodic output signal is a TTL output whose rate is user programmable from 2.5 MHz to
less than 1 Hz.
5.10 1 PPS IN BNC (-GPS, -IRIG)
The 1 PPS input BNC accepts an external 1 PPS signal which can be used as the TYMSERVE's
timing source.
5.11 10 MHz IN BNC (-GPS, -IRIG)
The 10 MHz input BNC is not currently used.
5.12 SPARE1 AND SPARE2 BNC (-GPS, -IRIG)
Two spare BNC holes are provided for special applications which may require extra input/output
connectors.
5.13 GPS ANTENNA CONNECTOR (-GPS)
The GPS antenna connector is installed on the -GPS version only. This 15 pin high density 'D'
connector (male) carries the signals from the GPS antenna to the TYMSERVE.
5.14 CHANNEL 1 - 8 OUTPUT BNCs (-GPS, -IRIG with -TDM option)
The 8 BNCs labeled 'CH 1 OUT' through 'CH 8 OUT' are the 8 buffered time code outputs for
those systems equipped with the -TDM option only. The TIME CODE OUT BNC also carries
the time code output, but this output also drives the buffer's input, so if it gets shorted out then all
8 buffered outputs will be lost.
