ML2439A is a four channel Power Meter which accepts input from Anritsu USB power sensors, processes and displays measurements simultaneously.

The ML2439A Peak Power Meter supports the following USB power sensors:

MA244xxA – Peak Power Sensors
MA243xxA – CW Sensors
MA242xxA, MA241xxA – True RMS Sensors

ML2439A benchtop power meter has a front panel multi-touch display and keypad to configure the instrument for measurements. A 50 MHz test source output is also provided on the front panel for calibration. ML2439A provides a GPIB and ethernet interface for remote operations.

When used with the MA244xxA USB peak power sensors which feature 195 MHz video bandwidth, the ML2439A can capture and make power measurements of very narrow pulse modulated signals as well as wideband periodic modulated signals.

With the MA243xxA CW USB power sensors the MA241xxA, and the MA242xxA TRMS USB power sensors, the ML2439A provides accurate RMS power measurement capability.

Capture/display/analyze peak and average/RMS power
Synchronous multi-channel measurements with MA244xxA sensors
Frequency range : 10 MHz to 50 GHz (sensor dependent)
Video bandwidth: 195 MHz for periodic signals
100,000 measurements per second measurement speed
