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 inde-
pendently) cable delays or other latencies in the STANAG output. Available Offset range is
–500 to +500 ms in 5ns steps.
PPS 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
page 201.
PPS Offset (ns) : Used to account for 1PPS cable delays or other latencies in the 1PPS out-
put. Available Offset range is –500 to +500 ms 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 10 V
levels) signal lines.
NOTE – SecureSync starts numbering I/O ports with 0 (only 1PPS and 10 MHz out-
puts start at 1, because of the built-in outputs).
