The microwave switch is also called a radio frequency switch, and realizes the function of controlling the conversion of a microwave signal channel. An RF (radio frequency) and microwave switch is a device to route signals at high frequencies through the transmission path. Radio frequency and microwave switches are widely used in microwave test systems for signal routing between instruments and devices under test.

When the test is needed, the qualified reference value is the basis for testing the detected object and judging whether the detected object is qualified or not. The system forms qualified reference values in two ways, one is to use a physical object as a reference, and the other is to use a specific numerical value as a reference. The present system allows for setting a certain "offset" for a qualifying reference value. The meaning of the offset is to add or relax the qualifying reference value by several dB. I.e. tighten or loosen the pass criteria of the test results by several dB. The specific offset may be set by an administrator user.

In actual engineering, the termination state of the shield is dependent on the assembled state between the cable shield and the connector. Thus, the present embodiment provides a cable shielding effectiveness test in two states. One is the inspection of the shielding effectiveness of the cable itself, and the other is the inspection of the shielding effectiveness of the cable assembly. The shielding effectiveness of the cable assembly refers to the actual shielding effectiveness of the cable after assembly with the connector.
In forming the reference values, the reference values in the respective states are formed separately. The two states differ in the manner in which the hardware is assembled. The shielding effectiveness of the shielded cable is formed by collecting data through physical testing.
