Page 8: Chapter 2 Working Principle
Tel: 886.909 602 109 Email: sales@salukitec.com www.salukitec.com 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. - Page 9 Tel: 886.909 602 109 Email: sales@salukitec.com www.salukitec.com 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.
