Multi-Channel RF Power Measurement with Flexible USB Sensor Support
The Anritsu ML2439A is a benchtop RF power meter designed for simultaneous multi-channel power measurement using Anritsu USB power sensors.
The ML2439A provides two active measurement channels as standard and can be expanded to four channels with Option ML2439A-0004. Depending on the connected sensor, the platform supports CW, True RMS, peak, pulse, and statistical power measurements for RF and microwave applications.
2 to 4 Channels
Two channels standard with expansion to four active channels.
10 MHz to 50 GHz
Overall frequency coverage depends on the connected USB power sensor.
High-Speed Peak Analysis
Up to 100,000 measurements per second and 100 ps time resolution in supported configurations.
A 5-inch WVGA multi-touch display provides graphical and numeric measurement views, including continuous, pulse, and statistical display modes. LAN remote control is supported, while GPIB is available as an option for integration into automated test systems.
Expandable Multi-Channel Architecture
Provides two active measurement channels as standard and supports expansion to four channels with Option ML2439A-0004.
Flexible USB Power Sensor Support
Supports compatible MA244xxA peak, MA243xxA CW, MA242xxA True RMS, and MA241xxA True RMS USB power sensors, allowing the measurement configuration to be selected for the required signal and frequency range.
Peak and Pulse Analysis
When used with compatible MA244xxA peak power sensors, the ML2439A supports peak, average/RMS and pulse measurements for narrow-pulse and wideband modulated signals.
CW and True RMS Measurement
MA243xxA CW sensors and compatible MA241xxA and MA242xxA True RMS sensors provide measurement configurations for CW, multi-tone and digitally modulated signals.
Pulse and Statistical Measurement Modes
Measurement processing includes automatic pulse measurements, marker measurements and statistical analysis with CCDF display capability.
Synchronous Multi-Channel Measurement
Compatible MA244xxA sensors support synchronized measurements across multiple channels for comparative pulse and timing analysis.
Trigger and Averaging Control
Trigger modes include Normal, Auto, Auto Peak-to-Peak and Free Run. Trace averaging can reduce displayed measurement noise during supported pulse and statistical measurement operation.
Touchscreen and Remote Operation
A 5-inch WVGA multi-touch interface supports graphical and numeric displays. LAN and SCPI remote control support automated test environments, with GPIB available as an option.
Integrated 50 MHz Test Source
A front-panel 50 MHz test source provides a convenient reference for checking supported power sensor operation.
