4314C, RF Wattmeter with Peak Envelope Measurement
4314C
PEP Broadband RF Wattmeter
Broadband Power with Peak Envelope Measurement
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.
Why Choose the 4314C?
Accurate PEP Measurement
Capture peak power on AM, SSB, and TV signals with built-in peak detection.
Switchable Power Modes
Easily toggle between average (CW) and peak readings.
Built on the Bird 43 Platform
With Bird’s plug-in elements, you can adapt to different frequency bands and power levels.
How It Works
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.
