Signature Control: Used to control when the signal will be present. This function
allows the modulation to stop under certain conditions, see also "Signature Control"
on page161.
TOD Format: The user-selectable format to be 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 10
V 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
independently) cable delays or other latencies in the STANAG output. Available Off-
set range is –500 to +500ms in 5ns steps.
Configurable settings under 1PPS Output are:
PPS Signature Control: Used to control when the signal will be present. This func-
tion allows the modulation to stop under certain conditions, see also "Signature Con-
trol" on page161.
PPS Offset (ns): Used to account for 1PPS cable delays or other latencies in the
1PPS output. Available Offset range is –500 to +500ms in 5ns steps.
PPS Edge: The operator can select if the output signal is a rising or falling edge
pulse.
PPS Pulse Width: Configures 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: Selects signaling on either RS-485 or TTL (supporting up
to 10V levels) signal lines.
