Abstract :
Fast and sensitive simultaneous measurement of many signals by means of multi-channel coherent receiver is described. All received signals are of different modulating frequencies, synchronous to one reference frequency. The ratio of all modulating signals periods to reference period is an integer. Two practical applications of multi-channel coherent receiver are given: multipoint measurement of electromagnetic field distribution with MST method and two-channel EPR spectrometer.
