Chapter 3 Functions and Operations

Test Connector Panel

The connectors and indicators located on the test panel are listed and described below. 12.5 to 15 Vdc @ 1100 mA input to power the unit or for battery charging.

WARNING

When using the AC-DC Adapter, always use a three-wire power cable connected to a three-wire power line outlet. If power is supplied without grounding the equip- ment in this manner, there is a risk of receiving a severe or fatal electric shock.

Battery	Illuminates when the battery is being charged. The indicator automatically shuts
Charging	off when the battery is fully charged.
External	Illuminates when the Site Master is being powered by the external charging unit.
Power
Serial	RS232 DB9 interface to a COM port on a personal computer (for use with the
Interface	Anritsu Software Tools program) or to a supported printer.
RF Out	RF output, 50 impedance, for reflection measurements.
RF In	RF input 50 impedance for transmission loss or gain measurement.
RF Detector	RF detector input for the Power Monitor.
