Introduction Chapter 1 Introduction TPM7 3140 Panel TPM1 The Transmitter Power Monitor (TPM) is the latest broadcast solution from Bird. Calibrated coupling ports and accurate power measurement combined in the same unit provides for easy use and accurate readings. The TPM is the first inline power monitor that can be calibrated 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.

Installing & Operating Instructions - TPM Chapter 2 Installing & Operating Instructions - TPM FWD Port Test Port To Source Figure 1 TPM Calibration Cover RFL Port TPM1 Shown Communication Connector Operation LED Calibration Cover Note: Figure shown with terminations assembled. To Load Note: The label on the top of the unit identifies the connectors and ports.
Bird Electronics Corporation Installing the TPM The TPM has two RF connectors (Source and Load) that connect to the transmission line, three test port connectors that are type N female connectors (Forward, Reflected, and Test), and one nine-pin subminiature communication connector (DB-9 Male). 1. Do the following: • • • Connect the RF connector labeled Source to the transmitter side of the transmission line. Connect the RF connector labeled Load to the antenna or load side of the transmission line.
Installing & Operating Instructions - TPM Normal Operation Note: Coupler ports must be terminated to ensure accurate power measurements. Terminate both forward and reflected coupler ports in 50 ohms. Failure to terminate these ports will result in inaccurate power measurements. 1. Install the TPM to the transmission line. Refer to “Installing the TPM” on page 4. 2. Apply DC input power to the TPM. 3. Apply RF power to the TPM. 4. Use a voltmeter to measure the forward voltage and reflected voltage.

Installing & Operating Instructions - 3140A Panel Chapter 3 Installing & Operating Instructions - 3140A Panel The 3140A is the standard display and power supply for the TPM. It comes in both 4 Channel TPM and 8 Channel TPM models. It fits in a standard 2U rack and requires a single 15V power supply (supplied with panel).

Bird Electronics Corporation FWD/RFL Meter Provides visual indication of measured power for selected TPM. Meter Adj Pot Provides full scale meter calibration. Channel Selector Selects either one of four (3140A4) or one of eight (3140A8) connected TPM’s. Power Button Applies DC input power to panel meter. Zero Calibrate Switch Grounds pin 9 to Zero calibrate the selected TPM. DB9 Connection Interface connection to TPM’s. Provides power and Zero adjust to connected TPM’s.
Calibration Chapter 4 Calibration CAUTION A Bird Calibration Kit is recommended for this procedure. Performing a calibration with anything other than a Bird Calibration Kit voids Bird’s accuracy guarantee. Performing a field calibration will void any remaining warranty on this product. Bird recommends waiting until the terms of the warranty have passed before performing a field calibration.
Bird Electronics Corporation Passive Calibration Calibrate the TPM on the transmitter it is monitoring. Also a reference power meter is needed to measure the output of the test port on the TPM (model 7006A250). This calibration can be performed while transmitting on air (forward only) or into a dummy load. Coupling calibration data for the TPM is also needed.
Calibration Active Calibration The active method will recalibrate the TPM completely. This procedure will void the calibration and accuracy specifications for the unit. The accuracy will be based on the accuracy of the reference power meter used for this procedure. In addition to the equipment needed for the active calibration, a Bird 6A340-ADJ Potentiometer Adjustment Tool to adjust the potentiometers on the TPM is also needed.
