F90 – Code Output Configuration
F90 – Code Output Configuration
Use function F90 to configure the time code output format (IRIG-A, IRIG-B, IRIG-B120 IEEE
1344 or NASA 36) and modulation type (AM or DC) on the XL-GPS’s standard CODE
output.
The factory settings for F90 are IRIG-B and AM.
Although the factory configuration outputs UTC time in 24-hour format, the following can be
used to modify the code output of F90 for non-standard applications:
• “F2 – 12/24 Hour Format” on page50 selects between a 12 or 24-hour time format.
• “F69 – Time Mode” on page90 selects between the following timescales: Local,
Standard, GPS, UTC, and TAI.
