MA24108A/MA24118A sensors

Anritsu Co. has introduced a microwave USB power sensor that provides accurate average power measurements from 10MHz to 18GHz over 60dB of dynamic range.

The MA24108A/MA24118A USB power sensors employ a dual-path architecture to achieve True-RMS measurement similar to a thermal sensor over the entire frequency and dynamic range. They can measure CW, multi-tone and digitally modulated signals used in commercial and aerospace/defense systems.

Both MA24108A/MA24118A sensors can either internally trigger or receive an external trigger signal, allowing them to conduct multi-slot and burst average power measurements of TDD waveforms, typically found in GSM, WiMAX and TD-SCDMA signals.

The MA24108A/MA24118A do not require a separate module for triggering. They have built-in external trigger circuitry with an MCX connector interface to receive triggers from external stimuli. The power sensors incorporate a microcontroller, signal conditioning circuitry, ADC and power supply. The MA24108A/MA24118A provide users with three modes of operationcontinuous average, scope, and time slot. All three modes can be accessed via PowerXpert or through remote programming commands. PowerXpert is Windows-based data analysis and control software developed by Anritsu.

The MA24108A is priced at $2,695 while the MA24118A is at $2,995. Delivery is four weeks ARO.
