Saluki S3502 series spectrum analyzer is adopted with the compact portable box structure, which has advantages of small size, light weight, low power consumption and convenient carrying. The broadband millimeter-wave receiver miniaturization integrated design technology, whole phase locking technology based on the broadband VCO, full digital intermediate frequency design technology, and microwave composite multilayer circuit board design technology are adopted for this product, thus realizing high performance indicators and ensuring the economical efficiency of the product. 

The S3502 series spectrum analyzer series currently consists of four types of products. The full spectrum of the product is equipped with a preamplifier, so that it has very high receiving sensitivity at any frequency point. For its performance indicators, it has excellent average noise level and phase noise indicator as well as the high scanning speed. For its measurement function, it has the option modes including the interference analyzer channel scanner, AM/FM/PM analyzer, and power meter, as well as a variety of measurement functions including the channel power, occupied bandwidth, adjacent channel power, audio demodulation, emission mask and carrier-to-noise ratio. This product can be used for the test and maintenance of the aviation, spaceflight, wireless communications and radar signals and devices, and it can also be used for the research, development and production of electronic products and the teaching experiment of scientific research institutes.


Typical Applications 

Test of Components and Parts

The S3502 series spectrum analyzer can be used for the test of parameters and indicators including the gain, frequency response, frequency conversion loss and insertion loss of the components and modules including the amplifier, filter, mixer, attenuator, cable and directional coupler.


Test and Diagnosis of the Transmitter and Receiver

The S3502 series spectrum analyzer has a number of measurement function modes including the spectrum analyzer, interference analyzer, AM/FM/PM analyzer, power meter, and channel scanner, and it also has a number of measurement functions including the channel power, occupied bandwidth, adjacent channel power, carrier-to-noise ratio, field strength, and emission mask; therefore, it can provide the comprehensive spectrum analysis and diagnosis service for the test of the transmitter and receiver.
