ST-7631 1GHz Vector Network Analyzer

ST-7631 1GHz Vector Network Analyzer features high accuracy and large dynamic range, which adopted Direct Digital Synthesis (DDS) signal generator and multi-receiver technique. So it can quickly measure the important index such as transmission, reflection, phase and group delay. 7631 is the perfect tool to test linear or nonlinear equipment of RF system (Radio Station, CATV, communication receiver or other wireless communication systems).

7631 is ideal for testing of narrowband filters, sound surface wave parts, amplifiers, antennas, impedance transforming subassembly, cable etc. Also automatic conformity testing and rapid testing is favorite and useful for volume production.

In addition, the test result can be saved, printed or transferred to PC. Also the test result can be recalled at any time in order to do a contrastive measurement
