The RFeye® SenS Portable is a lightweight, portable I/Q recorder for high-fidelity, long-duration RF recording and signal extraction from 9 kHz to 8 or 18 GHz. It has a 100 MHz real-time bandwidth and can store up to 12 hours of spectrum recordings in its internal 25.6 tbyte SSD. The DeepView software interface allows users to quickly find and extract the required signals. This system is ideal for capturing live signals in their native environment without sacrificing RF recording quality. The SenS Portable allows users to capture complex intermittent, low-power, short pulse duration signals that hide next to the desired ones. The system has 1 Hz that provides the highest signal quality for analysis and post-processing, and a 4-lane Thunderbolt 3 port allows gapless 16-bit streaming up to the full 100 MHz instantaneous bandwidth. It measures 10.9 x 5 x 6.5″ and weighs 7 lb. 6 oz. with dual SSDs.
