The XLi first synchronizes to IRIG-B-120 w/ IEEE1344 when the Time Quality control bits are = 0000.
The XLi remains synchronized (Locked) while the Time Quality control bits are 0000 through 0101 (ETE
< 10uSec). The XLi utilizes the IRIG-B-120 BCD TOY, IEEE1344 year, leap second, and leap second
pending bit as the UTC epoch. The XLi time format selection remains on the XLi including the Daylight
saving time offset.
INPUT:
• Amplitude (AM): 0.5 Vp-p to 10 Vp-p, 100 k
Ω to ground
• Ratio (AM): 3:1 ±10%
•Qty: 1
• Connector: BNC female
Time Code Input IRIG-B000 w/ IEEE1344
The selectable Code input has an additional selection for IRIG-B-000 w/ IEEE1344. Configuration is via
the Keypad / Display, RS232/422 and the Network port via telnet and HTML.
IRIG-B-007 IS DEFINED IN IRIG STANDARD 200-04 AS:
• Format B 100 pps
• 0 = Pulse width code
• 0 = No carrier/index count interval
• 0 = BCD TOY,CF,SBS
IEEE1344 IS DEFINED IN IEEE1344-1995(R2001) ANNEX F AS:
See section TIME CODE OUTPUT IRIG-B120 W/ IEEE1344 for definitions
XLI SYNC:
The XLi first synchronizes to IRIG-B-120 w/ IEEE1344 when the Time Quality control bits are = 0000.
The XLi remains synchronized (Locked) while the Time Quality control bits are 0000 through 0101 (ETE
< 1uSec). The XLi utilizes the IRIG-B-120 BCD TOY, IEEE1344 year, leap second, and leap second
pending bit as the UTC epoch. The XLi time format selection remains on the XLi including Daylight
saving time offset.
Input:
• Amplitude (DC): Logic Low < 1.25V >0V
