Anritsu MA2491A Wideband Peak and Average Power Sensor, 50 MHz to 18 GHz

Wideband peak and average power sensor covering 50 MHz to 18 GHz, with 20 MHz video bandwidth, for ML2480 and ML2490 series power meters.

Frequency Range: 50 MHz - 18 GHz
Video Bandwidth: 20 MHz

Overview

The Anritsu MA2491A is a wideband power sensor in the MA249xA series. It is designed for use with the ML2480 and ML2490 series power meters and covers a frequency range of 50 MHz to 18 GHz.

The sensor measures peak power, crest factor, average power, rise time, fall time, maximum power and minimum power, and provides statistical data on wideband signals. This makes it suitable for characterizing radar and modulated communication signals.

When used with ML2480 and ML2490 series power meters, the sensor supports a sampling rate of 64 MS/s and a 20 MHz video bandwidth. It connects to the device under test through a precision N(m) RF connector with a hexagon coupling nut, so it can be attached with a standard torque wrench.
