WISCO International (Bird- 4391A / 4380A)

The ruggedly built, multifunction Model 4391A RF POWER ANALYST ® features a digital display, microprocessor based operation, and simplified, push button control.

This is a general-purpose wattmeter well suited to two-way communications, avionics and radar, telemetry, and standard radio and television applications.

Reads forward and reflected CW or FM power in watts or dBm.

Calculates SWR, return loss in dB and percent modulation.

Measures peak power for pulses as narrow as 0.8 µs.
