3656A Vector Network Analyzer Introduction: The 3656A/B/D vector network analyzer is suitable for wireless communication, cable TV, education and automotive electronics. It can be used to measure the performance of RF components such as filters, amplifiers, antennas, cables, and cable TV taps. The product adopts Windows operating system; it has error calibration function, time domain function and fixture simulator function; it has various display formats such as logarithmic amplitude, linear amplitude, standing wave, phase, group delay, Smith circle, polar coordinate, etc. Provide a variety of calibration methods, including frequency response, single port, response isolation, enhanced response, full dual port, fast SOLT calibration and electrical calibration; multi-channel multi-window display; with USB interface, LAN network port, GPIB interface, VGA interface. It can quickly and accurately measure the amplitude, phase and group delay characteristics of the S-parameter of the device under test, and has efficient and powerful error correction capability. Features: With a dynamic range of up to 125dB for accurate measurement of high rejection ratio devices; The 3656A is available with a 75Ω test port impedance option for cable TV component measurements; The 3656A/B/D has a four-port option that allows all 16 S-parameter measurements on a four-port network with a single connection and balanced parameter measurements; Note: The 3656A/B four-port option is an external device 2813A Very low trace noise gives network analyzers a higher test accuracy; Provides up to 64 independent measurement channels for fast execution of complex test scenarios; Powerful data analysis capabilities, such as ripple test, bandwidth test, limit test and other functions, to facilitate user-qualified judgment and improve test efficiency; Standard time domain analysis function; The fixture simulator can simulate a variety of measurement occasions for scientific research and production, and obtain corresponding measurement results in a fast and real-time manner; LAN, GPIB interface for remote control and system interconnection with four USB ports. typical application: 1. Mobile communication product production test The 3656A/B vector network analyzer frequency range can meet the production test requirements of mobile communication products. It has the characteristics of fast scanning speed, large dynamic range and small size. It is very suitable for mass production testing of factories and can be used for filters, amplifiers, etc. Testing of RF components such as antennas and cables, and optional 75Ω test components for performance measurement of cable TV components. 2. Passive multi-port devices and balanced device testing The 3656A/B vector network analyzer and the 2813A S-parameter test set are built into a four-port vector network analyzer. With a single connection, all 16 S-parameter measurements of the four-port network can be realized. It is very suitable for high-volume production test of multi-port devices in the factory. With balanced parameter measurement function, using three test ports or four test ports for full three-port or full four-port calibration, select the corresponding working mode (single-ended-balanced network, single-ended-single-ended-balanced network, Balanced-balanced network), the mixed S-parameters of the balanced device can be obtained.
