8101-4TRX Keithley Fixture
The 8101-4TRX is a fixture from Keithley. A fixture is a kind of electronic test equipment that continuously runs tests on a piece of equipment. Fixtures test electronic components, circuits, chips, and software. Engineers use fixtures to hold the equipment under test (EUT) in place and run tests using controlled electronic signals.

The 8101-4TRX test fixture is a metal case with four female triaxial connectors (SMU1–4) and a latch on the outside. Inside the test fixture is one 4-pin device holder (transistor socket). The inner conductor of each triax connector is wired to the closest pin on the 4-pin device holder. The inner shield of the triax connectors are “no connects.” The triax connectors’ outer shield is connected to the test fixture’s metal case.
NOTE: It is safe to use the test fixture without an additional safety barrier if the connected instrument has a Safety Interlock that can disable any high voltage ranges capable of sourcing greater than 42V, such as the Keithley Model 4200.
