Chapter 2 Working Principle

The S3302 series spectrum analyzer consists of 4 mutually independent function modules with standard interfaces, namely microwave/millimeter-wave frequency conversion module, frequency synthesis module, IF signal processing module, and data processing, display and control module. Such a design facilitates maintenance of the main unit and replacement of the parts, and also significantly reduces the re-debugging workload of the main unit after the module replacement. The hardware scheme of the main unit is as shown in Fig.1.

2.1 Microwave/Millimeter-Wave Frequency Conversion Module
It is mainly used for receiving and down-conversion of the input signals of the microwave and millimeter-wave frequency band. The input signals will enter the frequency conversion module through the blocking module and 50 dB programmable step attenuator. The RF signals of 9kHz – 20 GHz and broadband local oscillator signals of 6 GHz – 12 GHz (or its second harmonic) are mixed to produce three second IF signals, namely 6,540.25 MHz of the first band (RF frequency is 9 kHz – 5.35 GHz), 1,740.25 MHz of the second band (RF frequency is 5.35 GHz – 13 GHz) and 3,340.25 MHz of third band (RF frequency is 13 GHz – 20 GHz), and then output 140.25MHz IF signal to the IF channel plate through down-conversion of the third-stage mixer. The signals above 20 GHz frequency band are mixed with the first LO signal after the preamplifier and subsection switching filter to produce first IF signal (5 GHz – 16.5 GHz).The first IF signal and RF signals of 9kHz – 20 GHz are switched into the second-stage mixer after switching by a single-pole double-throw switch, and the frequency conversion scheme is the same as the 5 GHz – 16.5 GHz. The microwave /millimeter-wave frequency conversion module directly affects the frequency conversion loss, noise factor, image frequency and off-band signal suppression and gain compression of the main unit, which consists of the broadband microwave/millimeter-wave switch, low-noise broadband preamplifier, high performance broadband microwave/millimeter-wave mixer, microwave/ millimeter- wave switch filter module, low power consumption LO amplifier and multiplying circuit and microwave switch filter module.

2.2 Frequency Synthesis Module
The frequency synthesis module is mainly used to provide the required LO signals to the three mixers in the microwave/millimeter-wave frequency conversion module and the fourth mixer in the IF signal processing module. It consists of seven phase-lock loops of 5.3 GHz – 5.55 GHz first LO, 6 GHz – 12 GHz second LO, 3,200 MHz third LO and 109 MHz fourth LO, which will directly determine the phase noise, sweep speed, sideband stray, etc. of the main unit.

2.3 IF Signal Processing Module
It is mainly used to carry out amplification and IF gain modulation of 140.25 MHz third IF signal output by the microwave/millimeter-wave frequency conversion module, and then make it enter the acoustic surface wave filter to suppress the out-of-band frequency, and obtain the fourth IF signal by mixing the third IF signal after gain adjustment on the third IF channel with the fourth local oscillator and make it as the AD converter input sampling signal. After AD sampling, it will output the LVDS level to the data processing, display and control module for IF filtering, video detection, digital down- conversion and video filtering, etc., and finally convert it to the testing curve and display it on the LCD.

2.4 Data Processing, Display and Control Module
It includes the switch power conversion, digital signal processing, display and touch screen driver, all kinds of user input and output interfaces required by the main unit and logic control functions of each unit circuit on the main unit. The data processing, display and control module is mainly used to control the circuit of each module to complete the measurement of the spectrum analyzer and the processing and display of the measurement data. It also includes auxiliary functions including the processing of keyboard and touch screen input information, peripheral control, parameter transformation, data and status storage and recall, measurement result output and cursor, as well as statistical analysis and functional support of LAN and USB interfaces.

   Click the indexes to be tested, and click Start Test. Attention:
   ① In case of measurement and display of the average noise level and remaining response, a 50Ω load shall be connected at the RF port. The indicators including test frequency range, third-order intercept point, 1 dB gain compression and standing-wave ratio can only be manually tested.
   ② In case of initial measurement of the reference level, scale fidelity and total level uncertainty, the power meter shall be connected for calibration. No recalibration is needed when another spectrometer is tested.
   (4) After the test of all indexes is completed, click Save Data to save the test results in the form of word files.
