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
