7072-HV Keithley Switch Card
- Two 1300V, sub-picoamp current paths
- Six 200V, 20pA paths
- For use with Model 2410 and Model 237 SMU
- 3-lug triaxial connections
- Compatible with Models 707A, 707B, 708A, and 708B
The Keithley 7072-HV is designed to switch lowlevel, high-voltage, and high-impedance signals for semiconductor parametric tests on wafers and devices. This unique design provides two signal paths capable of switching 1300V with less than 1pA of offset current. The two C-V paths may be used for measurement of capacitance voltage characteristics from DC to 1 MHz or for switching low currents with a common ground. Four additional high quality signal paths with less than 20pA offset current provide for signal switching to 200V.
Connections are 3-lug triax with the outer shell connected to chassis for safety and noise shielding. The center conductor is fully surrounded by the inner conducting shield to provide fully guarded measurements with higher isolation and improved measurement speed and accuracy.
