Abstract:
1. A connection apparatus for connecting a measurement apparatus and a device under test, which is a semiconductor device, the connection apparatus comprising: switching means, connected to the device under test, for receiving a control signal from controlling means; a preamplifier connected to the switching means; first connector that is connected to the preamplifier and that is connectable to first measuring means for measuring a first electrical characteristic of the device under test; and second connector that is connected to the switching means and that is connectable to second measuring means for measuring a second electrical characteristic of the device under test; wherein the switching means comprises at least one switch that switches between a first wiring configuration for electrically connecting the first measuring means to the device under test via the first connector and the preamplifier and a second wiring configuration for electrically connecting the second measuring means to the device under test via the second connector in accordance with the control signal from the controlling means, the first wiring configuration being suitable for measuring the first electrical characteristic and the second wiring configuration being suitable for measuring the second electrical characteristic; and the preamplifier amplifies current signals and/or voltage signals for the first measuring means.
