B&K Precision RFM3004-GPIB – 4 Channel RF Power Meter (includes GPIB)

Description
BK Precision RFM3004-GPIB – 4 Channel RF Power Meter (includes GPIB)
RF power meter
4 channels / includes GPIB
Compatible with RFP3000 series USB RF peak power sensors (sold separately)
Capture/display/analyze peak and average power
Independent or synchronous multi-channel measurements
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
Wi-Fi and wireless communication signal analysis

Characterization and compliance testing of Wi-Fi and LTE chipsets and devices involves significant challenges for design and test engineers. With multiple-input, multiple-output (MIMO) architectures and channel bandwidths up to 160 MHz, testing is complex, especially when measuring RF power per channel and time alignment between channels. The RFM3000 Series enables packet power measurements to be performed independently on multiple synchronous or asynchronous transmit chains with a common timebase shared among sensors.
Between marker measurements

Use markers to define a portion of the waveform on which to make measurements. “Between Marker” measurements are ideal for monitoring specific portions of a packet over long intervals.
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.
Addressing radar measurement challenges
Secondary Surveillance Radar (SSR)

Design, verification, troubleshooting and maintenance of secondary surveillance radar (e.g. IFF-based radar) has never been more demanding. Proper design and operation of SSR systems is critical to the safety and security of aviation. The RFM3000 Series can be used to easily and accurately capture SSR waveforms. Markers enable measurements on specific portions of the waveform.
Rise time and resolution

Industry-leading rise time (< 3 ns) enables characterization of the most demanding radar signals. Utilize the superior 100 ps time resolution to zoom and uncover signal characteristics that might otherwise be missed. Pulse measurements Users can take advantage of the RFM3000 Series automated pulse measurement feature to measure and calculate 16 common power and timing parameters and display the parameters of interest: rise-time, fall time, pulse width, off-time, period, pulse repetition frequency, duty cycle, pulse peak, pulse overshoot, pulse average, waveform average, top level power, droop, bottom level power, edge delay, and pulse edge skew between channels. Front Panel USB host: Connect up to 4 USB sensors for multi-channel measurements Sync port: Sync ports to source or receive triggers for timing and synchronization 5-inch WVGA touch display: Multi-touch display with intuitive user interface Intuitive control: One touch to quickly access presets and favorite functions Measurement modes: Touch to select Continues, Pulse or Statistical mode, and select between Graph and Text RF out: Test source to verify sensor operation Rear Panel Optional GPIB interface External trigger input Auxiliary sensor Sync inputs LAN interface: LAN connectivity to ethernet HDMI interface: HDMI output for remote front panel display High performance USB power sensors (sold separately) The RFM3000 Series Power Meter utilizes RFP power sensors with industry leading performance and capabilities. All RFP sensors incorporate Real-Time Power Processing technology, which virtually eliminates gaps in measurement suffered by other power sensors and enables industry leading measurement speeds. In terms of RF performance, the RFP3000 Series Real-Time Peak Power Sensors are the fastest responding sensors with 3 ns rise times and 195 MHz of video bandwidth. These sensors can be found in the accessories section of this page.
