Large dynamic range

Vector Network Analyzer TW4600 has a dynamic range of 125dB (IFBW=10Hz) for accurate measurement of device with high suppression ratio.

Extremely low trace noise

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

Time-domain analysis function

The analyzer can measure the time-domain characteristic of DUT by means of time-domain software so as to test the performance indicators of DUT comprehensively, such as cable fault location and length test

Powerful data analysis function

It has such functions as filter automatic statistics, limit test, ripple test and bandwidth test, which makes the loss, ripple and suppression very clear and facilitates hopping filter debugging.

Typical Applications:

Production test of mobile communication products The frequency range of Vector Network Analyzer TW4600 can meet the demand of production test of mobile communication products. It has such features of fast sweep speed, wide dynamic range and compact size which is very suitable for the test of mass production of factory. The vector network analyzer can be applied to the test of RF devices, such as filter, power amplifier, antenna and cables. The 75? test assembly is also available to characteriz the device of CATV.


Passive multi-port device and balanced device test A 4-port vector network analyzer can be built with Vector Network Analyzer TW4600 and TW 2813A S parameter test set. The 4-port vector network analyzer can test the whole 16 S parameters of 4-port network through one single connection and is very suitable for the mass production test of multiple port devices. It has balanced parameter test functions, make 3-port or 4-port calibration, select the corresponding operation mode (single port-balanced network, single port-single port-balanced network, balanced network-balanced network), and then you can gain the mixed Sparameters of balanced devices.
