TDEMI ULTRA

Ultra high performance: Best RF performance. Lowest noisefloor. The fastest FFT-based receiver on the planet & the fastest superheterodyne receiver on the planet – all at the same time.


The TDEMI ULTRA product line stands for highest performance and due to its various operation modes it can be used in a vast range of applications, e.g. also for measurements and testing according to telecommunication standards as ETSI – as well as for general analysis of signals as well – all this can be done fully gapless in real-time with an absolutely unique instantaneous bandwidth of 685 MHz. It is very easy and cost-efficient in upgrading its frequency range as well as by a various number of other extensions which can be integrated into the instrument also step by step. The frequency ranges are 6 GHz, 18 GHz, 26.5 GHz or 40 GHz respectively.
