MORGAN HILL, CA, May 29, 2026 – Anritsu has released the ML2439A power meter for engineers testing RF and microwave systems that use multiple signal types and sensor configurations. The benchtop and rackmount instrument works with up to four Anritsu USB power sensors and supports RMS, pulse and peak measurements across applications such as Wi-Fi, Bluetooth, WiMAX and radar development.
Key Features and Specifications
- Frequency Range: 10 MHz to 50 GHz, depending on the USB sensor model
- Supported USB Sensors: Up to four Anritsu USB power sensors at once, including MA244xxA peak power sensors, MA243xxA CW sensors, MA242xxA and MA241xxA True RMS sensors
- Dimensions: Chassis measuring 3.5 in x 8.3 in x 11.2 in (H x W x D), suited for benchtop and rackmount installation
- Measurement Modes: RMS, pulse and peak measurements on a single unit
- Display: Graphical and text views for modulated and continuous wave signals
- Interfaces: GPIB for legacy systems and ethernet for network connectivity
- Security Options: Removable internal microSD memory and USB boot capability
SCPI Control for USB Sensors
The ML2439A supports Standard Commands for Programmable Instruments (SCPI) for Anritsu USB power sensors. The command interface lets automated test systems control power measurements through the meter and integrate the instrument into existing test setups.
Simultaneous Power Measurements
The meter can run RMS, pulse and peak measurements at the same time when used with Anritsu USB power sensors. It displays results for modulated and continuous wave (CW), signals in graph and text formats.
Wideband Signal Measurement
The ML2439A uses USB sensor to define its measurement capability. When paired with MA244xxA USB peak power sensors, it measures pulse-modulated signals and periodic modulated signals. These sensors provide 195 MHz video bandwidth for complex signal measurements.
With MA243xxA CW sensors and MA241xxA or MA242xxA True RMS sensors, the ML2439A supports RMS power measurements across an input range from -60 dBm to +20 dBm. The instrument can test digitally modulated signals used in Wi-Fi, Bluetooth and WiMAX, and pulse signals used in radar system development.
Benchtop Use and Security
The ML2439A includes a front-panel multitouch display and keypad for benchtop operation. It also provides a 50 MHz test source output for calibration. The instrument includes GPIB for legacy test-system integration and ethernet for networked test environments. For controlled test areas, users can remove the internal microSD memory and boot the meter from an external USB drive.
