The Gauss Instruments TDEMI ULTRA is the company's highest-performance full-compliance EMI receiver series, available in four frequency configurations from 6 GHz up to 40 GHz, all starting from 9 kHz as standard and extendable to DC with the optional DC-UG upgrade. It combines an ultrafast superheterodyne stepped scan mode with up to 685 MHz fully gapless real-time bandwidth and a unique Multi-GHz Real-time Scanning capability covering the entire frequency range up to 40 GHz simultaneously — achieving a time resolution better than 100 ms over a 6 GHz span. Pre- and full compliance measurements are completed up to 64,000 times faster than conventional EMI receivers, with Band C/D Quasi-Peak from 30 MHz to 1 GHz completed in just 4 seconds. Unlike the TDEMI G series, the ULTRA adds an integrated oscilloscope mode (1 GHz bandwidth, 2.6 GS/s), 12V DC power input and an optional rechargeable battery pack — enabling true on-board testing in vehicles, aircraft and marine environments. Fully compliant with CISPR 16-1-1, ANSI C63.2, MIL-461 and DO-160 as standard. All models are field-upgradeable to higher frequency ranges and the EMI64k Automation Software Suite supports fully automated radiated and conducted emission testing. ISO 17025 and DAkkS accredited calibration are available.
