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 uniterruptible 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 on.

Chapter 1 Introduction
The Transmitter Power Monitor (TPM) is the latest broadcast solution
from Bird. Calibrated coupling ports and accurate power measure
ment combined in the same unit provides for easy use and accurate
readings. The TPM is the first inline power monitor that can be cali
brated in-line and on site minimizing downtime and optimizing on-air
time. In addition, a simplified interface allows for a high level of
customization and integration.

Purpose and Function
The TPM is used to measure power signals in broadcast systems. It is
used directly in line with the system being tested. It’s output provides
a linear DC voltage output from 0 to 4 volts allowing for a wide variety
of interface options. It’s in-line calibration capability allows for greater
accuracy in a single application (with an accurate power reference) and
its integrated non-directional coupler allows for signal analysis in
minimal space requirements. It is available in 7/8”, 1 5/8”, and 3 1/8”,
50 ohm lines for FM, VHF, and UHF broadcast frequencies.
When combined with a Bird model 3140A4 or 3140A8 Transmit Power
Meter (TPM) display, a complete adjustment system is achieved. The
display supplies a visual indication of Forward and Reflected power
being sampled by the inline TPM. Multiple TPM’s can be selected
(only one per channel setting) to give the operator an overall condition
of the transmitter system.
