| In this invention, a test system includes a tester and a switching module for connecting any pin to the tester for testing a device-under-test (DUT), the test system has a rectifying device between the ground of the DUT and the ground of the switching module in order to isolate the DUT from the switching module, thereby blocking unwanted current flowing between the DUT and the switching module to ensure the correctness of the testing.Since the ground of the switching module is not directly connected to the ground of the DUT and the tester, the rectifying device will keep the voltage difference between the ground of the switching module and the DUT in a range between zero and the cut-in voltage of the rectifying device, thereby allowing single-ended signals to be used between the switching module and the tester or the DUT. | ||||||

| Various embodiments of the system and method relate to improvements in co-channel interference mitigation in shared spectrum environments operating under the aegis of a Spectrum Access System and companion database. Implementation orchestrates, detects, and obtains noise measurements from a potentially-affected receiver utilizing programmed reduction of transmitted power from a potential interferer when the two entities connect over the Internet or other communication network. Receivers and transmitters may use the method with the same or different Physical Layers (PHYs) and protocols. In one embodiment, a momentary reduction of transmitter power is noted during which putative interference is measured at the receiver. In another embodiment, an isolated burst is sent from a not-yet commissioned transmitter to contemporaneously detect possible interference at an operating receiver. A third embodiment can be used to measure and mitigate interference from a stationary mobile transmitter. A fourth embodiment establishes hosting for potential interference recognition as a service. | ||||||
