HUGIN 4000 standard configuration supports monitoring receiver mode with narrowband DDCs. Each receiver input can monitor an  80 MHz band anywhere from 2 MHz to 6 GHz. The narrowband DDCs can be configured individually during run-time. Narrowband IQ data can be streamed as complex IQ data with 54 effective bits
or as demodulated audio data. For applications requiring a DDC wider than 40MHz an optional wideband DDC (per RF input) with full 80MHz bandwidth can be added. As an option scanning  receiver mode can be added to HUGIN 4000. For applications requiring optimized scanning rates multiple receiver inputs can be reconfigured from monitoring to scanning receiver mode. Besides independent tuning, HUGIN 4000 supports phase coherent tuning. This paves the way for beam forming and direction finding applications in a single receiver system.
