Datasheet

Overview

The Anritsu Power Master MA24510A is a USB-powered mmWave power analyzer that makes simple, numeric, frequency-selective average power measurements from 9 kHz to 110 GHz. Its measurement range reaches down to -90 dBm, and it can measure the amplitude of up to six signals at once. The RF input is a W1 male (1.0 mm) connector.

The Power Master uses a receiver-based architecture rather than the thermal components found in many mmWave sensors. This shortens measurement times and makes the measurement frequency-selective, so power is measured only in the frequency band of interest. The instrument is slightly larger than a smartphone and takes up little bench space.

PowerXpert software

The analyzer is controlled from the PowerXpert PC application, which handles the general settings (measurement mode, center frequency, span and resolution). In Power Hunter mode, the user sets a frequency range and the Power Master finds the six highest CW amplitudes and their frequencies. Channel Monitor mode tracks the CW amplitude or channel power of up to six channels, each up to 20 MHz wide, at the same time.

Use cases

The Power Master can be used for stand-alone measurements or as part of a system for calibrating vector network analyzers. Because it can measure very low power levels, it suits over-the-air testing of mmWave signals with high propagation loss. Mounting holes let it attach directly to probes for over-the-air or on-wafer testing.
