AV3656 A/B Vector Network Analyzer

AV3656 A/B vector network analyzer is applicable to fields of radio communications, cable TV, teaching and automotive electronics etc. It can be used for performance measurement of RF components such as filter, amplifier, antenna, cable, and cable television sub connectors etc. It adopts Windows operating system, and has functions of error calibration, time domain and fixture simulator; It supports multiple display formats such as logarithmic amplitude, linear amplitude, standing wave, phase, group delay, Smith chart and polar coordinates etc.; It provides multiple calibration types including frequency response, single port, response isolation, enhanced response and full dual-port, rapid SOLT calibration and electrical calibration; It is capable of multi-channel and multi-window display; It is designed with USB interface, LAN interface, GPIB interface and VGA interface. It can rapidly and accurately measure the amplitude, phase and group delay characteristics of the DUT S-parameter, with efficient and powerful error correction capability.

 AV3656 A/B Main Features:

  • Dynamic range up to 125dB; accurate measurement on high rejection ratio devices
  • 75Ω test port impedance option for cable TV components measurement
  • 001dBrms trace noise enables the network analyser with higher measuring accuracy
  • Up to 64 independent measuring channels that can implement complex testing schemes rapidly
  • Powerful data analysis functions, such as ripple test, bandwidth test and limit test, convenient for user to judge the conformity and improve the test
  • 4-port extension option to work together with 4-port extension equipment; can test the whole 16 parameters of 4-port network through a single connection, also capable of balance parameter test
  • Time domain analysis function as the standard configuration
  • Fixture simulator to simulate various R&D situations to rapidly get the real-time test results
  • LAN and GPIB interface, capable of remote control and system interconnection, 4 USB interfaces

AV3656 A/B Large dynamic range

With dynamic range up to 125dB (IFBW=10Hz), AV3656 A/B is capable of accurate measurement on devices with high rejection ratio.


AV3656 A/B Ultra -low trace noise

 Trace noise is lower than 0.001dBrms (IFBW=3 kHz), which minimizes measurement error.


AV3656 A/B Time-domain analysis function

 The analyzer can conduct time-domain measurement on DUT via time-domain software so as to comprehensively test the performance of DUT, such as cable fault location and length measurement.


AV3656 A/B Powerful data analysis function

It has multiple analysis functions, such as limit test, ripple test and bandwidth test, filter automatic statistics etc., which can clearly test the loss, ripple and rejection and facilitate the debugging of frequency hopping filter.


AV3656 A/B Typical Applications:

Production test of mobile communication products

The frequency range of AV3656 A/B vector network analyzer can meet the demand of production test on mobile communication products. It has advantages of high sweep speed, wide dynamic range and compact size which is very suitable for the test of mass production in factories. AV3656 A/B can be applied to the test of RF components such as filter, amplifier, antenna and cables. The 75Ω test assembly is also available for performance test of CATV devices.

Test of passive multi-port device and balance device

 A 4-port vector network analyzer is composed by AV3656 A/B vector network analyzer and AV2813A S parameter test set. It can test the whole 16 S parameters of 4-port network via one single connection, thus is very suitable for the mass production test of multi-port devices in factories. It has balance parameter test function: after the full 3-port or full 4-port calibration using 3 or 4 test ports, choose the corresponding operation mode (single port-balance network, single port-single port-balance network, balance-balance network), then you can gain the mixed S-parameters of balance devices.
