Introduction

Anritsu offers the world's most comprehensive range of power meters. The ML2490A series has the performance required

or narrow fast rising-edge pulse power measurements (e.g., radar), while the ML2480A series is suited for Wideband power

easurements on signals such as W-CDMA, WLAN, and WiMAX. The ML2430A series of power meters are designed for

m CW applications, offering a combination of accuracy, speed and flexibility in a low cost package.

lso available are five different families of power sensors with frequency coverage to 50 GHz and dynamic range up to 90 dB.

A Most of the power sensors can work in either pulsed/modulated or CW mode (the ML2480/90A series meters offer both modes).

n choosing a power sensor, several factors must be considered, including: frequency range, dynamic range and the modulation.

I The rise time of the sensor should also be chosen to match the rise time of the modulation.
