RF power meters and sensors

Here’s a sampling of RF power meters and sensors on the market. Click on the model numbers or names to view product pages.

The N1914A two-channel power meter from Keysight Technologies can take up to 400 measurements/sec and covers the frequency range from 9 kHz to 100 GHz. It accepts a wide range of power sensors.

 

The Boonton PMX40 power meter can make up to 100,000 measurements/sec from 4 kHz to 40 GHz.

Anritsu’s ML2496 pulse power meter makes average, min, max, peak, crest, and PAE (power added efficiency) power measurements up to 65 GHz. The company also manufactures CW power meters.

 

The Rohde & Schwarz NRQ6 Frequency Selective Power Sensor covers 50 MHz to 60 GHz and measures power down to -130 dBm. It connects to a PC or network through an Ethernet port getting its power through PoE or over a USB link.

 

The PM1890 USB power sensor/meter from GEM Microwave connects directly to a laptop PC over a USB link. It measures average and peak power, covering 50 MHz to 18 GHz and takes up to 15,000 measurements/sec.

 

For antenna power measurements used in broadcast applications, portable RF power meters such as the PMR 3030 EXT from LBA Group inserts inline and measures forward and reflected power up to 1000 W at frequencies to 1 GHz.

 

Combining a USB power sensor to a handheld RF/microwave analyzer such as this FieldFox from Keysight lets it measure RF power.
