Chapter XII Operating Principle

S3302 series spectrum analyzers have four operating bands: 9kHz - 20GHz, 9kHz - 26.5GHz, 9kHz - 32GHz and
9kHz - 44GHz, and various measurement functions such as spectrum measurement analysis, field strength
measurement, occupied bandwidth measurement, channel power measurement, adjacent channel power
measurement, tune listening and IQ capture. With options for interference analysis, AM-FM-PM signal
demodulation analysis and USB power measurement, the RF signal parameters such as the frequency and
amplitude can be measured. The functional block diagram of S3302 series spectrum analyzer is shown in Fig. 12-1.

Fig. 12-1 Overall Functional Block Diagram

System hardware can be divided into the microwave MMW frequency conversion module, frequency synthesizer
board, IF channel board, CPU board, display, keyboard, battery, etc.
The microwave MMW frequency conversion module includes two parts: 60dB program-controlled step attenuator
and switch filtering and frequency conversion part. The attenuation value of the program-controlled step attenuator
