With the Compact Receiver ESMC, a universal and multipurpose receiver for radiomonitoring applications has been produced in a compact size that was thought not possible up to now. The new receiver is only half the size of customary 19" multipurpose receivers of 3 height units but its technical data are even superior to those of such units.
ESMC is a heterodyne receiver with a second IF of 21.4 MHz. In spite of the compact design, no compromises have been made in the operating concept. For reducing the total signal load, the tuners are each provided with a tracking preselection filter. High-level mixers ensure high immunity to intermodulation. The low oscillator reradiation is the result of elaborate filtering. An advanced synthesizer concept featuring a very low phase noise allows switching times of less than 1 ms. This permits highly efficient scanning and fast status assignment in slave operation.
