Options - Option 03 Four Additional Configurable Outputs -DISCONTINUED-

Summary Information

Adds four more individually-buffered BNC outputs, jumper-selectable to any signal available on the clock Main Board.

Full Description

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

Specifications

General

• Output Connectors: BNC-type RF connectors (4).
• Default Configuration if the clock is equipped with modulated IRIG-B: The two BNC connectors on the right¹ are modulated IRIG-B and the two BNC connectors on the left¹ are unmodulated IRIG-B.
• Default Configuration when the clock is NOT equipped with modulated IRIG-B: All four BNC connectors are unmodulated IRIG-B.

¹ When looking at the rear panel from the back of the clock.

Analog Outputs

• Output Type Operational amplifier (LF353) output, with 557-ohm series resistor.
• Available Outputs: Note: All outputs available on clock Models 1088B, 1093B/C, and other clocks as noted.
• IRIG-B, Modulated: IRIG format B time code, modulated onto 1 kHz 10 Vpp sinewave carrier. Available on clock Model 1093B/C when equipped with Option 92, IRIG-B Modulated Output.
• Deviation (1088A/B): ± 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).

Digital Outputs

• Output Type: High-Speed CMOS (74HC126), 0 V to 5 V, with 47 ohm series resistance.
• Available Output: Note: All outputs available on Model 1088B and other clocks as noted.
• IRIG-B: IRIG format B time code (unmodulated).
• 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 adjustable from 0.01 seconds 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 minutes 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 carrier,
  and data transitions on time mark.
