Electrical Type: Either RS-485 or TTL (supporting up to 10 V levels) signal
lines.
Time Scale: Used to select the time base for the incoming time code data.
The entered Timescale is used by the system to convert the time in the
incoming data stream to UTC time for use by the System Time. The avail-
able choices are:
UTC: Coordinated Universal Time ("temps universel coordonné"), also
referred to as ZULU time
TAI: Temps Atomique International
GPS: The raw GPS time as transmitted by the GNSS satellites (as of
22-August-2023, this is 18 seconds ahead of UTC time).
A local clock can be set up through the Time Management Page; see
"Local Clock(s), DST" on page199. Local timescale allows a Local
Clock to apply a time offset for Time Zone and DST correction.
Offset: Provides the ability to account for STANAG Line (TOD1 and TOD2
independently) cable delays or other latencies in the STANAG input. Avail-
able Offset range is –500 to +500ms in 5ns steps.
Stanag TFOM: The Time Figure of Merit for the input.
Under 1PPS Input:
1PPS Offset: Used to account for 1PPS cable delays or other latencies in the
1PPS input. The available Offset range is –500 to +500ms in 5ns steps.
PPS Edge: Indicates whether the output signal is a rising or falling edge
pulse.
PPS Electrical Format: Indicates whether the signal is synchronized to RS-
485 or TTL (supporting up to 10 V levels) signal lines.
