The cards install directly into the option slot <200V contact potential in the back panel of the Model 6517B . The cards are also compatible with the Models 6517A and 6517 . <1pa offset current The Model 6521 Low Current Scanner Card is a 10-channel multiplexer, designed for switching low currents in multipoint testing applications or when the test configuration must be changed . Offset Compatible with Keithleys 15 current on each channel is <1pA and high isolation is maintained between each channel (>10 W ) . Model 6517 and 6517a The Model 6521 maint ains the current path even when the channel is deselected, making it a true Electrometers current switch . BNC input conn ectors help provide shielding for sensitive measurements and make the card compatible with low noise co axial cables . The Model 6521 is well suited for automating reverse leakage tests on semiconductor junc tions or gate leakage tests on FETs . The Model 6522 Voltage/Low Current Scanner Card can provide up to ten channels of low-level current, high impedance voltage, high resistance, or charge switching . Although it is similar to the Model 6521 in many ways, the Model 6522s input connectors are 3-lug triax . The card can be soft- ware configured for high im pe dance voltage switching of up to 200V . Triaxial connectors make it possible to float the card 500V above ground and drive guard to 200V . Mo DEl 6521 sPECIf ICaTIoNs MoDEl 6522 sPECIf ICaTIo Ns ordering Information CHANNELS PER CARD: 10 .
