Safety Precautions
The following are general safety precautions that are not necessarily related to
any specific part or procedure, and do not necessarily appear elsewhere in this
publication. These precautions must be thoroughly understood and apply to all
phases of operation and maintenance.
WARNING
Keep Away From Live Circuits
Operating Personnel must at all times observe general safety precautions. Do
not replace components or make adjustments to the inside of the test
equipment with the high voltage supply turned on. To avoid casualties,
always remove power.
WARNING
Shock Hazard
Do not attempt to remove the RF transmission line while RF power is present.
WARNING
Do Not Service Or Adjust Alone
Under no circumstances should any person reach into an enclosure for the
purpose of service or adjustment of equipment except in the presence of
someone who is capable of rendering aid.
WARNING
Safety Earth Ground
An uninterruptible earth safety ground must be supplied from the main
power source to test instruments. Grounding one conductor of a two
conductor power cable is not sufficient protection. Serious injury or death
can occur if this grounding is not properly supplied.
WARNING
Resuscitation
Personnel working with or near high voltages should be familiar with modern
methods of resuscitation.
WARNING
Remove Power
Observe general safety precautions. Do not open the instrument with the
power applied.

Chapter 1 Introduction
The Bird 4044 Series Non-Directional Power Sensors are analog power sensors
designed for use with the Bird Channel Power Monitor (CPM).
The 4044 Series power sensors are typically used to measure forward average
power on a 50 ohm RF transmission line with a maximum 100 watt forward
power level in a frequency band with an overall range of 144 to 960 MHz. See
"Model Identification" on page 7
for specific frequency ranges and model
features.

Power Sensor Installation
This procedure is an example of one possible cable configuration, based on the
Connection Diagram
.
1. Disable RF power for transmission lines to be disconnected.
2. Connect transmitter RF output cable to the 4044 RF input.
3. Connect 4044's RF output connector to the Combiner input.
4. Repeat step 1 through 3 for any additional 4044 power sensors.
5. Connect a data/power cable from the CPM to each 4044 power sensor.
6. Configure the CPM. Refer to the CPM Operation Manual.
WARNING
Never attempt to connect or disconnect RF equipment from the
transmission line while RF power is being applied.
Leaking RF energy is a potential health hazard.
