Abstract
A measuring device ( ), for measuring the spectrum of a measured signal in several neighboring channels ( ) of a working channel ( ), includes a selective filter ( ) which damps the working channel ( ) more strongly than the neighboring channels ( ). Furthermore an analogue/digital converter ( ) is provided which detects the filtered measured signal from all the channels to be measured ( ) in a parallel and broadband manner and converts the above to a digital signal. An equaliser ( ) in series with the analogue/digital converter ( ), equalises the digital signal with a frequency response which is the reciprocal of the frequency response of the selective filter ( ).
