Patent ID: 7061260

Claim:
A calibration device for calibrating a tester channel of a tester device, comprising: a contact carrier comprising a first contact area and a second contact area insulated from the first contact area, wherein the first contact area is connectable to the tester channel being calibrated and the second contact area is connectable to one or more remaining tester channels of the tester device; and a connecting device for electrically connecting the first and second contact areas through a calibration line to the tester device; wherein the first contact area is contact-connectable to one of a plurality of contact-connecting needles of a needle card connected to the tester channel to be calibrated and the second contact area is contact-connectable to one or more remaining contact-connecting needles of the needle card which are connected to the one or more remaining tester channels; and wherein the contact carrier further comprises a planar substrate having a first conductive shielding layer disposed thereon and a first insulation layer disposed on the first conductive shielding layer, wherein the first and second contact areas are disposed on the insulation layer.
