USB Power Sensors Have 60-dB Dynamic Range To 18 GHz

The MA24108A and MA24118A microwave USB power sensors deliver accurate average power measurements from 10 MHz to 8 GHz (MA24108A) and 10 MHz to 18 GHz (MA24118A) over a 60-dB dynamic range. A “dual-path” architecture, which makes true-rms measurements similar to a thermal sensor over the entire frequency and dynamic range, enables the sensors to measure CW, multi-tone, and digitally modulated signals used in commercial and aerospace/defense systems. Both 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 sensors feature three operating modes: Continuous Average, Scope, and Time Slot. Scope mode allows power measurements to be displayed with respect to capture time of up to 300 ms. It is particularly useful when measuring non-periodic waveforms with video bandwidth up to 50 kHz. The Time Slot mode can be used for TDMA waveforms. It breaks up the measurement into individual time intervals and calculates the average power reading of each. This feature allows entire frames of various communication signals to be analyzed with as many as 128 slots. The MA24108A sells for $2695, and the MA24118A costs $2995. Delivery is in four weeks.
