The second generation of the new NRA Analyzer family comprises the 19 inch rack-mount NRA-3000-RX (9 kHz to 3 GHz) and NRA-6000-RX (9 kHz to 6 GHz) RF analyzers. Both are equipped with an RF module that has been developed for low phase noise and low intrinsic interference. The devices analyze RF signals up to 6 GHz in the frequency or time domain and simultaneously exhibit receiver characteristics, enabled by a new high frequency receiver module.

The analyzers can yield spectrums of up to 600,000 frequency points with time resolutions as fine as 30 nanoseconds. Rapid transmission of large quantities of data is possible in binary format. Unusually high channel bandwidths can be captured with the intermediate frequency bandwidth up to 32 MHz. With software, users can freely define up to 500 channels or frequency ranges to be monitored. The demodulation function makes it possible to directly hear FM, AM, USB, LSB and CW signals using external headphones.

All NRA-RX devices are 1U (1.75") high and weigh less than 5 kg. With a power consumption of less than 20 VA, they operate silently and do not require forced ventilation, making them suitable for mobile systems or confined spaces. They can also be integrated into practically any test and monitoring environment with the Ethernet interface and ASCII, plain text remote control commands. A 10 MHz reference input is provided for synchronization to the system frequency; stand-alone operation with a PC is also possible.

The devices are primarily designed for use in automated and remote controlled measuring systems. They are particularly suitable for radio surveillance and monitoring, demodulation and decoding, spectrum occupancy, coverage, signal analysis and classification, detection of illegal transmitters and SIGINT (COMINT and ELINT).
