RFWattmeter™ Series2021-04-09T07:08:05-07:00

RFWattmeter™

The RFWattmeter™ measures and passes signals from 100 kHz to 10 MHz, up to 2,000 watts full scale, with minimal loss.
The RFWattmeter™ is enclosed in a handheld plastic housing with BNC connectors, a DC power connector, a micro-B USB connector, and an optional SMB connector for triggering an oscilloscope or other DAQ device.

Calibration Details

Calibration is performed using an absorptive power meter as a reference standard. An included certificate of calibration lists calibration conditions and reading accuracy deviations. A detailed test report will be provided upon request at an additional charge, which includes plots of the RFWattmeter’s frequency response and power linearity.
