Signal is detected and its composition must be periodic. With respect to the work in the time domain oscilloscope mode, it is displayed in the time domain amplitude spectrum analyzer is displayed in the frequency domain signal amplitude out. Each spectral component of a signal with a spectrum analyzer will be observed. The same signal oscilloscope display, only observe a waveform. The spectrum analyzer is actually a third-conversion superheterodyne receiver Sweep. The signal of any frequency within the range of 0.15 ~ 1050MHz, by the input socket (3) to the first mixer, where it is the first local oscillator (voltage controlled oscillator filter f = 1350 ~ 2350MHz) to signal mixing. The first local oscillator frequency and the difference between the input signal frequency of the signal (f LO = a fa into the first intermediate frequency) of the first intermediate frequency, 1350MHz it by tuning in on the three-cavity bandpass filter, then enter the RF amplifier; then into the second mixer; second local oscillator reference frequency is generated by a 12MHz crystal oscillator with a first intermediate frequency 1350MHz, the frequency synthesizer generated after the second local oscillator frequency and the second difference between the first intermediate frequency of the mixer and the frequency of the second intermediate frequency (29.875MHz). The second IF bandpass filter on PCB board, into the third mixer, 2.75MHz IF signal produced after the third mixer, after the third IF amplifier, by 20kHz or 400kHz bandpass filter. Logarithmic output video signal, either directly or through a low pass filter, to the Y-axis amplifier. After Y axis logarithmic signal amplifier is connected to the CRT after the Y deflection plates. x deflection plate is 8MHz when the base signal generated by the crystal after several minutes to control the frequency of 43Hz integrating circuit generates a sawtooth voltage, the x-axis amplifier drive later.
