Large dynamic range
With dynamic range up to 125dB (IFBW=10Hz), 3656A/B/D is capable of accurate measurement on devices with high rejection ratio.

Ultra -low trace noise
Trace noise of 3656A/B/D is ultra-low, which minimizes measurement error.

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

Powerful data analysis function
It has 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 help for conduct hopping filter debugging.

TYPICAL APPLICATIONS
Production test of mobile communication products
The frequency range of 3656A/B/D 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. 3656A/B/D 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/B/D VNA provide 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.

Notes: For 4-port option of 3656A/B, it’s external device 2813A
