The Bird 4314C builds on the legacy of the Model 43 with added circuitry to measure peak envelope power (PEP)—a critical need for amplitude-modulated signals like AM broadcast, SSB, and TV video.
Compatible with Bird’s full range of plug-in elements and powered by internal batteries or an AC adapter, the 4314C is a field-proven wattmeter ready for both average and peak power readings across a wide frequency range.
Capture peak power on AM, SSB, and TV signals with built-in peak detection.
Easily toggle between average (CW) and peak readings.
With Bird’s plug-in elements, you can adapt to different frequency bands and power levels.
The 4314C uses a directional coupler and analog meter—like the Model 43—but includes active peak detection circuitry powered by two standard 9V batteries (or optional AC).
The internal electronics sample and hold the peak envelope voltage, which is then displayed on the analog meter scale. A front-panel switch allows you to toggle between average (CW) and PEP modes instantly.
Learn How to Read Your Meter Get Expert HelpMeasuring peak envelope power in AM, SSB, or TV video transmitters
Performing forward and reflected power checks in broadcast or LMR systems
Use in lab, field, or system test benches where accurate peak detection matters
Continuous power monitoring without interrupting system operation
PEP measurement captures the highest instantaneous power in modulated signals like AM or SSB—critical for proper transmitter tuning.
No. Just like other Bird wattmeters, it uses plug-in elements that define the frequency and power range—no charts or configuration required.
It runs on two 9V batteries for portable use or can be powered via an optional AC adapter.
Keeping equipment calibrated is the number one way to ensure performance and longevity. A Bird Calibration means we fully test your equipment and adjust it as needed to ensure it’s meeting specs.
For decades, Bird’s element-based wattmeters have set the standard for accuracy, durability, and technician-trusted performance. That legacy continues—but so does the evolution.
Whether you prefer the familiar reliability of plug-in elements or you're exploring the ease of new generation RF power measurement, Bird is here to support your journey.
