The TDEMI ULTRA 40 from GAUSS INSTRUMENTS is an EMI Receiver with a frequency range from 9 kHz to 40 GHz. It provides a fully integrated spectrum analyzer with a real-time analysis bandwidth of 685 MHz. This receiver utilizes GAUSS INSTRUMENTS' patented technology with advanced DSP concept in combination and includes ultrafast receiver scanning. It is ideal for use in labs according to civil standards (e.g. CISPR, EN, FCC Part 15, ANSI C63.2, ANSI C63.4), military standards (e.g. MIL-461G, but also its previous versions and revisions) as well as avionic standards (e. g. DO-160). This analyzer fulfills the CISPR 16-1-1 Ed 3.1 as well as all later editions and has been designed for pre-certifications as well as final certifications.

The TDEMI ULTRA 40 combines an ultrahigh-performance stepped scan mode with ultrahigh-performance technology and offers a large variety of configuration possibilities. It has a dynamic range of 100 dB (@0 dB attenuation and preselection off) which can be increased to more than 170 dB with an automatically stepped attenuator and an ultrahigh performance preselection. This receiver has a probability of intercept of 300 ps and can detect, measure, and investigate very short, intermittent signals or single events. It is a powerful measurement equipment for emission testing on the market and is also suitable for measurement and testing according to telecommunication standards such as ETSI.

For EMI measurements, the TDEMI® ULTRA 40 includes an extremely fast scanning speed. Pre- and full compliance measurements can be carried out by a factor of 64,000 times faster than with other solutions. For measurements using the quasi-peak detector the duration of a scan in the range from 30 MHz to 1 GHz is reduced from hours down to a few seconds for full compliance testing and product certification.

The TDEMI ULTRA 40 EMI receiver includes a user-friendly graphical user interface and a 10.4 inch touch screen and can be remotely controlled and fully automated via Ethernet (TCP/IP). It can operate on AC/DC supplies or by a battery pack and consumes 90 to 130 W of power. This flexibility enables it to perform on-board testing in vehicles, boats, or aircraft.
