J. -30dB Output
Do not reproduce or distribute.
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.
