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 available 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 July, 2015,
this is 17 seconds ahead of UTC time).
A local clock can be set up through the Time Management Page; see "Local Clock
(s), DST" on page158. 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 inde-
pendently) cable delays or other latencies in the STANAG input. Available 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 (sup-
porting up to 10 V levels) signal lines.
