TOD Format: The user-selectable format being used. Available formats include:
STANAG 4246 HQI
STANAG 4246 HQII
STANAG 4372 HQIIA
STANAG 4430 STM
STANAG 4430 XHQ
ICD-GPS-060A BCD
ICD-GPS-060A HQ
DOD-STD-1399 BCD
Electrical Format: Selects signaling on either RS-485 or TTL (supporting up to 10V levels)
signal lines.
Time Scale: Used to set the desired time scale (UTC, TAI, GPS, or Local). See above.
Offset (ns): Provides the ability to account for STANAG Line (TOD1 and TOD2 inde-
pendently) cable delays or other latencies in the STANAG output. Available Offset range
is –500 to +500ms in 5ns steps.
STANAG TFOM: The Time Figure of Merit for the output.
Under 1PPS Output, the following settings are displayed:
PPS Signature Control: Indicates whether the signal will be present. This function allows
the modulation to stop under certain conditions, see "Signature Control" on page141.
PPS Offset (ns): Used to account for 1PPS cable delays or other latencies in the 1PPS out-
put. 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 Pulse Width: Indicates the Pulse Width of the 1PPS output. The Pulse Width is entered
and displayed in nanoseconds (the default Pulse Width is 200 ms).
PPS Electrical Format: Indicates signaling on either RS-485 or TTL (supporting up to 10V
levels) signal lines.
