EK2000 series :

The R&S Series 2000 line includes transceiver and receiver systems for mobile and stationary use with powers of 150 Watt, 500 W and 1000 W. The series not only provides the full range of standard radiocommunications functions; it also offers a wide variety of applications by means of useful options. Communications take place in line with international standards. Fast and reliable data transmission as well as message handling allow the series 2000 to be integrated into modern multimedia systems, thus providing the basis for reliable, worldwide communications independent of existing infrastructures. It is possible to set up high-power broadband communications systems on the basis of the series components for transmissions on multiple channels with low frequency separation and in different emission modes.

High RF selectivity; the optional FK2020/FK2040 digitally tuned RF selectors with a tuning time of only 10 ms enable fast frequency changes. Selectivity is up to 40 dB at 10% frequency spacing in the transmission and reception mode, while far-off selectivity exceeds 70 dB. The input is protected against overvoltages up to 200V EMF.
