Automatic New Energy Detection

Wideband auto-detection techniques trigger parallel New Energy Alarms for real-time prosecution of even LPI emissions.

Wideband Scrollback Buffer

Rewind entire wideband stare or sweep bandwith to detect & classify emissions which less capable systems would miss.

Configure, Adapt & Modify

Open architecture for back end processing allows easy modification to suit dedicated tasks.

Integrated Wideband Receiver

CA-7851/V-UHF precision wideband digital receiver with 100 MHz real-time stare & mulitple handoff receivers.
