1. IN A SPECTRUM ANALYZER FOR A BAND OF SIGNALS, INCLUDING A SUPERHETERODYNE RECEIVER HAVING SCANNING LOCAL OSCILLATOR AND A HETERODYNE CONVERTER COUPLED TO SAID OSCILLATOR AND SAID SIGNALS FOR DERIVING AN I.F. FREQUENCY, AN I.F. AMPLIFIER CONNECTED IN CASCADE WITH SAID CONVERTER, AND AN OUTPUT VISUAL DISPLAY SYSTEM COUPLED TO SAID I.F. AMPLIFIER, THE COMBINATION OF SWITCH MEANS CONNECTED BETWEEN THE OUTPUT OF SAID I.F. AMPLIFIER AND THE INPUT OF SAID DISPLAY SYSTEM, A FREQUENCY DISCRIMINATOR COUPLED IN CASCADE WITH SAID I.F. AMPLIFIER, SAID DISCRIMINATOR HAVING A ZERO RESPONSE AT A MID-FREQUENCY OF SAID I.F. AMPLIFIER, MEANS FOR DERIVING A CONTROL SIGNAL FOR SAID SWITCH FROM SAID DISCRIMINATOR, SAID CONTROL SIGNAL ACTIVATING SAID SWITCH MEANS SO THE I.F. AMPLIFIER OUTPUT IS APPLIED TO THE RECORDER INPUT ONLY WHEN SAID DISCRIMINATOR IS RESPONSIVE TO I.F. FREQUENCIES WITHIN A PREDETERMINED BAND CENTERED BY SAID MID-FREQUENCY, SAID I.F. AMPLIFIER HAVING A CONSIDERABLY WIDER BANDWIDTH AT ITS HALF POWER POINTS THAN THE WIDTH OF SAID PREDETERMINED BAND SO THAT THE COMBINED GAIN OF SAID I.F. AMPLIFIER AND SWITCH IS SUBSTANTIALLY CONSTANT FOR ALL FREQUENCIES WITHIN SAID PREDETERMINED BAND.
