138 Options List
C.12.4 Digital Outputs
Output Type: High-Speed CMOS (74HCXXX), 0 to 5 volts, with 47 ohm
series resistance.
Pin Numbers: Output 1: pin 22
Output 2: pin 47
Output 3: pin 23
Output 4: pin 48
Available Outputs:
IRIG-B:
IRIG format B time code, 5 V CMOS (unmodulated).
IRIG-E: IRIG format E time code, 5 V CMOS.
IRIG-H: IRIG format H time code, 5 V CMOS.
IRIG-D/1 PPM: IRIG format D time code (1 pulse per minute), 5 V CMOS.
Rising edge on time.
10 MPPS: 10 MHz square wave, synchronous to the 1 PPS output.
5 MPPS: 5 MHz square wave, synchronous to the 1 PPS output.
1 MPPS: 1 MHz square wave, synchronous to the 1 PPS output.
100 kPPS: 100,000 PPS square wave, synchronous to the 1 PPS output.
10 kPPS: 10,000 PPS square wave, synchronous to the 1 PPS output.
1 kPPS: 1,000 PPS square wave, synchronous to the 1 PPS output.
100 PPS: 100 PPS square wave, synchronous to the 1 PPS output.
60 PPS:* 60 PPS square wave, synchronous to the 1 PPS output.
50 PPS:* 50 PPS square wave, synchronous to the 1 PPS output.
10 PPS: 10 PPS square wave, synchronous to the 1 PPS output.
1 PPS: 1 PPS (10 mS ”high”), synchronous to 1 PPS/GPS.
1 PPnnnS: 1 pulse per ”nnn” seconds (10 mS ”high”, synchronous to 1
PPS/GPS); ”nnn” corresponds to a number of seconds en-
tered by the user.
1 PPH: 1 pulse per hour, rising edge on time.
Out-of-Lock: 5 volt CMOS levels. Normally ”high” after acquisition of
satellite signals. Toggles ”low” nn minutes after loss of satel-
lite signal lock. Range for ”nn” is 00 to 99, and is set us-
ing the SETUP menu or RS-232C (refer to Chapter 6 and
Appendix C). Setting of 00 disables this function (output re-
mains ”high”).
* Available only with the Model 1088A/B series clocks.
