    Abstract: A direct current and a modulation signal are simultaneously applied to contact pads on a device under test, such as a laser diode. A probe and method of probing reduces signal distortion and power dissipation by transmitting a modulated signal to the device-under-test through an impedance matching resistor and transmitting of a direct current to the device-under-test over a second signal path that avoids the impedance matching resistor.

    Abstract: A probe station for probing a test device has a chuck element for supporting the test device. An electrically conductive outer shield enclosure at least partially encloses such chuck element to provide EMI shielding therefor. An electrically conductive inner shield enclosure is interposed between and insulated from the outer shield enclosure and the chuck element, and at least partially encloses the chuck element.
