- Anritsu has announced the launch of the ML2439A series power meter, which allows for the integration of up to four USB power sensors.
- This power meter covers a frequency range from 10 MHz to 50 GHz, depending on the USB sensor model used.
The ML2439A series power meter supports several sensor types, including the MA244xxA models (peak power sensors), the MA243xxA models (CW sensors), and the MA242xxA and MA241xxA models (true RMS sensors). Its compact housing (8.9 cm x 21.1 cm x 28.4 cm) allows for benchtop or rack mounting.
The device enables simultaneous RMS, pulse, and peak measurements, with results displayed graphically and textually for modulated and continuous (CW) signals. It features GPIB interfaces for integration with existing systems and Ethernet for modern connectivity. A security option allows the internal microSD memory to be removed and booted from an external USB drive, meeting enhanced security requirements.
This power meter supports SCPI (Standard Commands for Programmable Instruments) commands for USB sensors, enabling automated control of power measurements. This feature facilitates integration into test systems and improves operational efficiency.
Pulse-Modulated and Wideband Signal Measurements
Thanks to Anritsu’s USB sensors, the ML2439A series power meter can capture and measure narrow pulse-modulated signals as well as wideband periodic modulated signals. Combined with the MA244xxA series sensors (195 MHz video bandwidth), it enables complex signal measurements. With the MA243xxA (CW) and MA241xxA/MA242xxA (True RMS) series, it offers precise RMS power measurements over an input range from -60 dBm to +20 dBm.
These capabilities make it a suitable tool for testing digitally modulated signals, such as those used in Wi-Fi, Bluetooth, and WiMAX applications, as well as for pulse measurements in radar system development.
This benchtop wattmeter features a multi-touch screen and a front-panel keypad for configuring measurements. It offers a 50 MHz test source output for calibration.
