Abstract:
1. A pin card comprising: an input/output terminal to be connected to a device under test; a DC test unit configured to perform a DC test operation for the device under test; an optical semiconductor switch arranged such that a first terminal thereof is connected to an AC test unit configured to perform an AC test operation for the device under test, and a second terminal thereof is connected to the input/output terminal and the DC test unit configured to perform the DC test operation for the device under test, and configured to be capable of switching states, according to control signals input to a positive control terminal and a negative control terminal thereof, between a connection state in which the first terminal and the second terminal are connected to each other, and a disconnection state in which the first terminal and the second terminal are disconnected from each other; a first impedance circuit arranged on a signal path for the control signal to be input to the positive control terminal of the optical semiconductor switch; and a second impedance circuit arranged on a signal path for the control signal to be input to the negative control terminal of the optical semiconductor switch.
