New options for handheld RTSA support military, government applications

Anritsu Company recently announced the addition of two new options for its Field Master Pro real-time spectrum analyzer (RTSA) that address military and government requirements. One is a pulse analyzer that enables pulse profiling; the other is an option for removal of Wi-Fi and Bluetooth capabilities that enables secure operation.

The pulse analyzer option enables measurement of extremely narrow pulses, even at very low power, for the installation, maintenance and troubleshooting of defense radar systems. Pulses as narrow as 30 ns (typical), in accordance with IEEE 181-2011, can be automatically measured when the option is installed in the Field Master Pro MS2090A. For aerospace and defense engineers and technicians, this means accurate power measurements (i.e., average, peak, peak-wave, wave, pulse), pulse characteristics and first and second transition characteristics without the need for time-consuming setup.

In addition, the need for an external power sensor for pulse measurements is eliminated by the MS2090A’s 110 MHz real-time analysis bandwidth and -100 dBm noise floor. Measurements can be made on signals 60 dBm to 70 dBm lower than external sensors. Because the power sensors are broadband as compared to the MS2090A’s frequency-selective receiver, users are able to filter out pulses, interference and noise beyond the band of the signal of interest.

The Wi-Fi and Bluetooth removal option permanently takes away those capabilities via physical removal of the Wi-Fi/Bluetooth chip from the instrument motherboard. This eliminates wireless transmission by software, addressing the need for secure operating environments.

Anritsu notes that, even without the new options, the existing MS2090A provides support for military and government applications in a variety of ways. Its RTSA tools can accurately measure the amplitude of a single spectrum event as short as 2 µs and detect a single event as minimal as 5 ns, which is relevant for signals that are short in duration or that hop in frequency. The device is also compatible with the COMINT Consulting Krypto1000 Wideband Signal Analysis and Decoding Suite with IQ data. It performs capture and streaming of up to 110 MHz of IQ bandwidth across full 54 GHz, providing a broader range of RF IQ data for post-processing to deliver a deeper view of SIGINT and COMINT activity.
