Section 3 Operating Instructions

3-1 Introduction

This section contains operating instructions for the SPA9329-35 power booster amplifier.

3-2 Initial Start-Up & Operating Procedures

Operating controls, indicators, and connectors located on the SPA9329-35 booster amplifier

module are listed in table 3-1 and corresponding locations for each are shown in figure 3-1. To

perform the initial start-up, proceed as follows:

1. Verify that all power and RF input and output cables are properly connected, per section 2.

CAUTION

Before applying power, make sure that the input and output of the amplifier are prop-

erly terminated at 50 ohms. Do not operate the amplifier without a load attached. Re-

fer to table 1-2 for input power requirements. Excessive input power may damage the

amplifier.

NOTE

The output coaxial cable between the amplifier and the antenna must be 50-ohm co-

axial cable. Use of any other cable will distort the output.

2. Turn on supply that provides +27 Vdc to the amplifier system.

3. Set the DC power ON–OFF switch to ON. The corresponding PWR and TMP LED indicators

should illuminate.

4. Apply the RF input signal.
