BK Precision RFM3002 - 2 Channel RF Power Meter (without GPIB)

The RFM3000 Series of meters work in combination with B&K Precision's RFP3000 Series of USB RF Peak Power Sensors to extend their capabilities and eliminate the need for a remote computer. This benchtop solution supports capturing, displaying, and analyzing peak and average RF power in both the time and statistical domains through an intuitive, multi-touch touchscreen display.

Two on-screen markers can be dragged over a waveform for greater measurement details. A selection of useful trigger options and channel synchronization settings provide the perfect tool set for working with multiple channel measurements.

Several models available

The RFM3000 in four configurations - 2 or 4 channels, as well as with or without GPIB. The following is overview of part numbers and features.

Measurement modes

Measurement modes can be quickly changed form Continuous to Pulse or Statistical modes with one touch.

Continuous mode

For simple, intuitive measurements of repetitive waveforms, the RFM3000 Series Continuous Mode of operation provides a numeric display of average, maximum and minimum signal powers.

Pulsed mode

Analysis of fast-rising single pulses or pulses with short pulse repetition intervals (PRIs) requires an instrument with sophisticated trigger and data acquisition capability. Within Pulsed Mode, more than 16 pulse parameters can be measured.

Statistical mode

Complementary Cumulative Distribution Function or CCDF plot shows the rate of occurrence of a specific crest factor for signals, such as those used in 5G, 4G/LTE, and Wi-Fi applications.

Addressing RF communications and radar measurement challenges

Peak-to-average power

By comparing the peak-to-average power ratio, or crest factor (CF), of input and output signals of an RF transmission chain, engineers can assess circuit linearity. Additional insight can be provided with the RFM3000 Series statistical mode Complementary Cumulative Distribution Function (CCDF) plot displaying the rate of occurrence of a specific CF. As an amplifier output compresses, the CF will reduce and the CCDF plot will move left.
