Bird's Transmitter Power Monitor (TPM) is used to measure power signals and perform spectral analysis of broascast systems. The TPM series can be calibrated during broadcast operation so there is never any need to remove from service, eliminating downtime.
In-line calibration assures that it retains the origional National Institute of Standards and Technology (NIST) calibration.
A power measurement solution designed for operation inside the transmitter or after the combiner
In-line calibration capability allows for greater accuracy in a single application (with an accurate power reference)
Accurately measures true average power for digitally modulated systems
7/8", 1-5/8", and 3-1/8", 50 Ohm line sections available for FM, VHF, and UHF broadcast frequencies
DB9 output provides a linear DC voltage output from 0 to 4 volts allowing for a wide variety of interface options
3140A4 DISPLAY OPTION
Avialable in a 4 channel configuration
When combined with a Bird model 3140A4 Transmit Power Meter (TPM) display, a complete sdjustment 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.
