C.4 Option 03: Four Additional Outputs –
C.4.1

General Description

Option 03 adds four rear-panel outputs, which may be configured to an available signals in the
1092A/B/C or 1093A/B/C series clocks. Note that there are many more jumper settings on the
Option 03 board than the 1092A/B/C or 1093A/B/C is capable of providing. The configuration
of the four outputs can be changed at any time via internal jumper settings.

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.
BNC-type RF connectors (4).
Operational amplifier (LF353) output, with 557-ohm series resistor.
Note: All outputs available on clock Models 1088B, 1084A/B/C,
1093A/B/C and other clocks as noted.
IRIG format B time code, modulated onto 1 kHz 10 Vpp sine wave
carrier. Available on clock Model 1093A/B/C when equipped with
Option 92, IRIG-B Modulated Output.
5 volts analog, corresponding to 1-PPS deviation channel A or B
(see individual clock Operation Manual). The proportion is 1 V per
10-µs deviation ( 50 µs full scale). Model 1088A/B only.
High-Speed CMOS (74HC126), 0 to 5 volts, with 47 ohm
series resistance.
Model 1093A/B/C output signals include unmodulated
IRIG-B, 1 PPS, Programmable Pulse, Out-of-Lock.
IRIG format B time code (unmodulated). Also available on
clock Models 1088B, 1084A/B/C and 1093A/B/C.
