MA24208A/MA24218A Specifications

Introduction

The MA24208A and MA24218A Universal USB Power sensors are designed to provide accurate average power
measurements from 10 MHz to 8 GHz and 18 GHz, respectively, over 80 dB of dynamic range. The sensors employ a
patented “triple path” architecture that provides True-RMS measurements over the entire frequency and dynamic range
(similar to thermal sensors), enabling users to make highly accurate average power measurements for CW, multi-tone,
and digitally modulated signals up to 18 GHz.

Features and Benefits

• Broad Frequency Range (10 MHz to 18 GHz): Ideal for general purpose, aerospace and defense, satellite and wireless

communications applications

• True RMS Measurements over 80 dB Dynamic Range: Enables average power measurement on CW, multi-tone, and digitally
modulated signals - independent of modulation bandwidth

• Best-in-Class Damage Protection (+30 dBm CW, +34 dBm peak < 10 µs): Protects instrumentation investment

• No Zeroing Required (for signals > –45 dBm) and Elimination of 1 mW Reference Calibration: Reduces test time and handling in

production while maintaining absolute accuracy

• Advanced Trigger Capabilities: Facilitates time dependent power measurements (for example, GSM, WiMAX, TD-SCDMA, and LTE)

• NIST Traceable Calibration: Provides high-accuracy measurements

• Easy to Use with PC or Select Anritsu Handheld Instruments: No benchtop power meter unit needed

• Silicone Protective Covering (removable): Provides additional field durability

• External Trigger Latching: For pulses as narrow as 20 ns
