INTRODUCTION

1.02.02 Rear Panel Connections

J. -30dB Output

The power meter portion of the COM3010 uses a 100W 30dB attenuator to dissipate power

on the heatsink on the back of the unit. The 30dB attenuated output is provided as a

convenience to allow safe connection of an external spectrum analyzer or other equipment.

For example if you transmitted 100W of power into the GEN OUT jack, 100W = +50dBm. The

output of the 30dB attenuator will now be +20dBm, which is within the range of what most

spectrum analyzers can safely handle.

K. Fuse

Fuse for AC line power. Replace with a standard 1A slow-blow fuse only.

L. AC Input

There is a 15VDC switching power supply internal to the COM3010 that can operate from a

wide range of AC voltages without having to set any jumpers. The power supply included can

handle a range from100 VAC to 240 VAC 50/60 Hz.

M. RS-232

The RS-232 jack is provided for remote control of the COM3010 and also firmware updates.

At one time the software was limited to 9600:8,n,1, as shown on the back panel, but now it

has the flexibility to choose a range of baud rates. See USER OPTIONS - Serial Port Options.

N,O. Battery Panel

Two thumbscrews are provided for easy removal and attachment of the rear battery panel to

access the Lithium Ion batteries.
