Typical Applications

Production test of mobile communication products

The frequency range of 3656A vector network analyser 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. 3656A can be applied to the test of RF components such as filter, amplifier, antenna and cables. The 75Ω test assembly of 3656A is also available for performance test of CATV devices.

Test of passive multi-port device and balanced device

3656A VNA provides 4-port test function . 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 balanced 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-balanced network, single port-single port-balanced network, balanced-balanced network), then you can gain the mixed S-parameters of balanced devices.
