on the power supply. set up a sygnal generator to have a sinusoidal ou put of 1 volt peak-to-peak and a frequency of approximately 455kHz, then connect it to the input socket of the Deruned Resonant Circuit(p35). Use your double-beamed oscilloscope to monitor the output from the transformer's secondary winding p39, together with the input signal to the detector at p35 Use tp35 to trigger the oscilloscope a Vary the frequency output of the signal generator either side of the present position and note that the amplitude of the signal at tp39 follows the frequency response shown in Figure 98. Moaator the detector's output signal at tp10 together with the input signal to the detector at tp35 gain use tp35 to trigger the oscilloscope Vary the frequency of the signal generator's output around 455kHz and see that the DC voltage level also follows the response curve in Figure 98. 8.4a Enter the maximum DC voltage level measured at rp40(in volts). if you bave access to a frequency meter, record the DC voltage at tp40 incoming frequencies from 20kHz below to 20kHz above the resonance frequency of the tuned circuit. Plot the DC voltage at mp40 against frequency and check that the response is similar to that shown in Figure 98. Carefully adjust the signal generator to provide the carrier frequency of 455kHz. By making very small adjustments whilst monitoring the DC voltage at rp40, check that this frequency occurs approximately halfway up the left-hand slope of the response. If it does not, it may be that T4 needs adjusting. To do this, follow the instructions given in Appendix 1"Adjustment of Tuned Circuits Disconnect the signal generator. We will now use the Detuned Resonant circuit Detector
