2.3.2 Antenna Input
The Model 1084A/B/C provides a type-F, GPS antenna input connector not only as the connection
point for GPS signal, but also supplies 5 volts to energize the antenna. It is equipped with a
threaded, type-F female connector.
Shown below is a diagram of the antenna connector. To check for this signal, use a small multimeter
and probe from the center pin of the connector to the threads. Voltage range is 4.9 to 5.1 Vdc. For
further information, see Chapter 4, Antenna and Cable Information.

2.3.3 Event Input
For timing external events based on the GPS-synchronized time, use the Event Input function with
two separate connectors: P3 (Standard I/O) and J2 (RS-232C). See Figure 5.1, which illustrates
the location of these connectors and jumpers.
