Introduction This section identiﬁes the connectors, controls, and displays found on the front and rear panels of the 1092A/B/C and 1093A/B/C series clocks. Take care to review all of these items prior to connecting cables to and conﬁguring these products.
Page 23: Front Panel Controls And Indicators
2.2 Front Panel Controls and Indicators Front Panel Controls and Indicators The front panels of the Model 1092A/B/C and 1093A/B/C series clocks are diﬀerent from one another because of the arrangement of LED indicators, display(s) and keypad. See Figure 2.1 to see the diﬀerence between these models.

Page 37: Gps Cable Data And Accessory Information
Available Antenna Cables and Accessories for Longer Runs Arbiter Systems oﬀers longer antenna cables for use with all models of clocks when the standard 15-meter (50-foot) cable is inadequate. For RG-6 cable runs greater than 250 feet, up to 500 feet, Arbiter oﬀers a 21-dB in-line ampliﬁer, P/N AS0044700.
Page 38 GPS Antenna and Cable Information Adjacent Signals Although the standard RG-6 style cable is triple-shielded and has excellent shielding properties, be cautious when routing near high power RF sources or alongside cables carrying high power RF, such as transmitter cables. In these applications, consider using RG-11 style cable (P/N WC0004900). Its quad-shielded design provides even more isolation.

Setting Internal Jumpers Introduction Jumpers in the the 1092A/B/C and 1093A/B/C series clocks are normally set up at the factory according default settings, or according to the purchase order if requested. If it should be necessary to change any jumpers or to enable an alternate function, follow the instructions in this chapter.

Page 67: Timing, Irig-B And Pulses
Timing Output Description When viewing the rear panels of the Model 1092A/B/C and 1093A/B/C, you will see a number of diﬀerent types of connectors as illustrated in Figure 8.1. Generally, there is a power inlet connector, a GPS antenna connector, two DB-9 serial connectors (one is an optional RS-232 port), one optional SPDT relay connector, one optional and two standard timing outputs.

Timing, IRIG-B and Pulses Figure 8.1: Rear Panel Descriptions – optional outputs may be shown 8.2.1 Inputs and Outputs – Port 1, Port 2, Port 3 Three, Phoenix-style, terminal connectors can supply timing signals to external equipment and may also be conﬁgured for input. Two of the outputs (Ports 1 & 3) are designed for digital signals and one (Port 2) for analog.
Page 69: Output Signal Description
The Model 1092A/B/C and 1093A/C transmit (IRIG) Format B with four variations as seen in Table 8.2. Note that with the newer IRIG Standard 200-04, two of the designations have changed: the older B000 has become B004 and B120 has become B124.

Timing, IRIG-B and Pulses 8.3.2 Modulated and Unmodulated IRIG-B Figure 8.2 illustrates the primary diﬀerences between modulated and unmodulated IRIG-B. You will notice that the while modulated IRIG-B is distinctive because of the 1 kHz sinewave carrier, it is similar to unmodulated IRIG-B since the peak-to-peak values of the carrier follow the same form as the peaks of the digital waveform, which contain the information.

ﬁrmware conﬁguration. Models 1093B/C and 1092B may be conﬁgured from the front panel and 1092A/C and 1093A must be conﬁgured through the RS-232 port. There are many available programmable pulse modes from which to choose that include setting the pulse width and time zone.
Page 72: Connecting The Outputs
Timing, IRIG-B and Pulses Connecting the Outputs All clocks come equipped with Phoenix-style, screw terminal connectors, which are compatible with twisted pair cabling. To attach, strip the wires bare, DO NOT tin with solder, insert into the correct screw terminal positions and tighten clockwise. To adapt coaxial cabling to the 1092/93 terminal connectors, use a BNC Breakout , or other similar adapter.
Page 73: Connecting Unmodulated Irig-B
8.4 Connecting the Outputs 8.4.4 Connecting Unmodulated IRIG-B To drive multiple loads from one unmodulated IRIG-B output, make sure that the loads are wired in parallel. A common term for this is “Daisy-Chaining”, however the idea is to drive all of these loads in parallel from a single output.
Page 74: Wire Losses
Timing, IRIG-B and Pulses 8.4.6 Wire Losses Another factor aﬀecting the available voltage is the resistive losses through the cabling. Wire has a certain resistivity associated with it that is determined by its metallic composition, and resistance determined by the diameter and length. For example, single-strand, 22 AWG (bare, enamel-coated) copper wire has a resistance of approximately 19.6 ohms per 1000 feet.
Page 75: Solutions
8.4 Connecting the Outputs Since electromagnetic waves travel slower through any cable, cable manufacturers normally specify cable with a velocity factor (VF), which is a percentage of the speed of light in free space, and characteristic of the speciﬁc cable. The Velocity Factor for the RG-6 cabling used by Arbiter Systems for GPS antenna connections, is about 83% of C.

Without Option 93 installed, the relay contact connector will be visible, however no contacts or related circuitry will be installed.

The time mark for a captured event will correspond to the leading edge of the start bit of the ﬁrst character in the RS-232C signal. This event mode can be both armed and interrogated for data over the RS-232C interface, allowing automated synchronization of an external computer or system.

C.15 Option 34: NTP/PTP Server Clock Jitter – is deﬁned as the root-mean-square (RMS) average of the most recent oﬀset diﬀerences, and it represents the nominal error in estimating the oﬀset (of the clock). Clock wander – is the RMS of exponentially weighted frequency diﬀerences. This is not used directly, but can, along with the jitter, be a highly useful monitoring and debugging tool.
Page 172: Ntp Authentication Page
Options List NTP Authentication Authentication involves advanced conﬁguration for NTP, and used to prevent tampering with the timestamps on the logs generated by devices. You can conﬁgure a device to authenticate the time sources to which the local clock is synchronized. When you enable NTP authentication, the device synchronizes to a time source only if the source carries one of the authentication keys speciﬁed by the ntp trusted-key command.
