C.4 Option 03: Four Additional Outputs –
Obsolete
109
IRIG-E:
IRIG format E time code.
IRIG-H:
IRIG format H time code.
10 MPPS:
10,000,000 pulse-per-second (PPS) square wave, synchronous to the
1-PPS output.
5 MPPS:
5,000,000-PPS square wave, synchronous to the 1-PPS output.
1 MPPS:
1,000,000-PPS 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.
IRIG-D/1 PPM:
IRIG format D time code (1 pulse per minute), rising edge on time.
1 PPH:
1 pulse per hour, rising edge on time.
1 PPS:
(10 ms “high”), synchronous to 1 PPS/GPS.
Programmable:
Outputs a single pulse at a preprogrammed time, or a continuous
pulse train having a period of one day or less. Pulse width is ad-
justable from 0.01 to 600 seconds.
Out-of-Lock:
Normally “HI” after acquisition of satellite signals. Toggles “LO”
nn minutes after loss of satellite signal lock. Range for “nn” is 00
to 99 minutes, and is set using the SETUP menu or RS-232C (refer
to clock Operation Manual). Setting of 00 disables this function
(output remains “HI”). This output follows the standard “Out-of-
Lock” function on the clock.
IRIG-B (Modified
Manchester):
IRIG format “B” time code, Manchester encoded with 1-kPPS car-
rier, and data transitions on time mark.

Case Removal
To change the configuration of Option 03, the top cover of the instrument must be removed.
Turn off the instrument, and disconnect the power cord. Using a T-25 Torx driver, remove the four
screws holding the cover (and rack mount ears, if used) in place, and lift the cover off.
WARNING
Do not remove the top cover while power is applied. Hazardous voltages are present
while the power cord is connected. Always disconnect the unit from the input power source before
removal of the top cover.
