High-Accuracy Handheld RF Power Meter

By DE Editors

Keithley Instruments, Inc. (Cleveland, OH) recently released the Model 3500 Portable RF Power Meter, a handheld RF power meter designed to make RF power measurements in both the field and RandD lab environments. This release adds to Keithley’s family of RF test and measurement solutions, which also includes the Model 2910 Vector Signal Generator and Model 2810 Vector Signal Analyzer.

It has a wide frequency range of 10MHz to 6GHz, and its large dynamic range of -63dBM to +20dBM enables the Model 3500 to measure signals either directly from the device under test or through layers of cabling and fixtures. A built-in power sensor eliminates the need for users to carry both an instrument and a separate sensor module. An internal power reference enables self-calibration.

The Model 3500’s absolute accuracy, as good as +/-0.21dB, enables more precise characterization of devices, tighter test limits, and more accurate fixture calibration. In the lab, the Model 3500 can be used as an RF power datalogger. Using normal or high-speed mode, it can capture and transfer data to a personal computer through its built-in USB interface. In addition, a number of averaging values can be used when the measured signal varies significantly with time.

The Model 3500 is capable of drawing operating power from batteries, an AC-DC converter module, or a computer via the USB interface. An optional belt-loop holster carrying case with shoulder strap is also available.

The Model 3500 Portable RF Power Meter is priced at $1,500.  For more information, click here.
