The TPM is used to measure power signals in broadcast systems and is used directly in line with the system being tested. Its output provides a linear DC voltage output from 0 to 4 volts allowing for a wide variety of interface options.
Its 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. The TPM 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.
In-situ calibration
- World Class first in-situ power measurement standard
- Calibrate during operation, while ON-AIR
- Never any need to remove from service which equates to no downtime
- Traceable to National Institute of Standards and Technology (NIST)
