TEST SYSTEM AND METHOD OF TESTING LINK PERFORMANCE Russian patent published in 2024 - IPC H04L43/50 

FIELD: physics.

SUBSTANCE: invention relates to communication testing. To this end, the system comprises: a printed circuit board with a combination of relays; simulation unit, wherein the simulation unit is located on a printed circuit board with a combination of relays; and an interface unit, wherein the interface unit is located on a printed circuit board with a combination of relays and is configured to connect a device under test (DUT); relays on a printed circuit board with a combination of relays are turned on/off to connect the DUT to a connected transceiver and an oscilloscope with program control in the simulation unit in order to test the DUT in the working environment simulated by the simulation unit; simulation unit also comprises an external channel, multimeter, programmable power supply device, four-quadrant signal shape amplifier, adjustable resistive/capacitive load with program control and a signal generator, the shape of which depends on different operating conditions, which are normal operating conditions, short circuit/open circuit conditions and general mode/differential mode noise conditions.

EFFECT: possibility of testing and verification for different operating conditions of various signal characteristics and operating characteristics under all operating conditions of the tested device.
