Electrical Type : Selects synchronization to either RS-485 or TTL (supporting up to 10 V
levels) signal lines.
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 +500 ms in 5ns steps.
TFOM Threshold : Under the STANAG protocol, the TFOM (Time Figure of Merit)
threshold value can be utilized as a means to validate timing data based on the TFOM.
For more information on TFOM, see "Configuring the Oscillator" on page 196.
