Anritsu Power Meters and Power Sensors: Accurate, Fast, and Affordable.

Power Meter Specifications ML2430A, ML2480B, ML2490A

The specifications in the following pages describe the warranted performance of the instruments for 25 ± 10 °C.
"Typical" specifications describe expected, but not warranted, performance based on sample testing. They do not guarantee the performance of any individual product. "Typical" specifications do not
account for measurement uncertainty.

Introduction

Anritsu offers the world’s most comprehensive range of power meters. The ML2490A series has the performance required for
narrow, fast rising-edge pulse power measurements (for example, radar), while the ML2480B series is suited for wideband
power measurements on signals such as W-CDMA, WiMAX, LTE, and WLAN. The ML2430A series of power meters are designed
for CW applications, offering a combination of accuracy, speed and flexibility in a low cost package.

Also available are seven different families of power sensors with frequency coverage up to 50 GHz and dynamic range up to
90 dB. Most Anritsu power sensors can work in either pulsed/modulated or CW mode (the ML2480B/90A series meters offer
both modes). In choosing a power sensor, several factors must be considered, including: frequency range, dynamic range, and
the modulation type. The rise time of the sensor should also be chosen to match the rise time of the modulation.

PowerMax™

PowerMax™ is a free graphical user-interface software for the ML2480B and ML2490A Power Meter Series.

PowerMax provides an enhanced visualization of instrument display and simplified remote control of the instrument, allowing:

• Continuous view of measurement traces in real-time

• Multiple gates and markers readings displayed at a glance

• Archiving or printing of data and plots for future analysis

PowerMax Requirements:

Hardware

• PC Processor: 1.5 GHz

• Ethernet Interface: 10/100BaseT LAN

• Memory: 1 GB RAM or greater

• Monitor: 1024 x 768 or greater resolution

Software

• Operating System: Windows XP, Service Pack 2 or higher

• Browser: Microsoft Internet Explorer 5.1 or higher

PowerSuite

PowerSuite is free software available for the ML2430A series power meters. This software is used to continuously view
measurement traces on the PC in real-time or to archive data and plots for future analysis. PowerSuite runs on a standard PC
running Windows® 95 or higher, via GPIB or RS232.
