ABSTRACT:
The invention relates to a measuring installation for a frequency analysis of signal levels within a large volume range which is to be extremely fast. The measuring installation has an intermediate frequency amplifier arrangement with two and more selective amplifiers (SV1, SV2, SC3) which are equipped in each case with an automatic amplification regulation. The loop is broad band and contains a controllable attenuator (PR1, PR2, PR3) and a variable-gain amplifier (RV1, RV2, RV3). The band width of the selective amplifiers connected in series is reduced step-by-step in the direction of the signal flow. The regulating variables of the variable-gain amplifiers are summed in an adder (Ad) and supplied to a signal level evaluation and display installation (AA).
