The 6522 is a switch card from Keithley.
Features:
10 channels of multiplex switching
Install directly in 6517B’s option slot
Choose from low current scanning or high impedance voltage switching with low current switching
<200μV contact potential
<1pA offset current
Compatible with Keithley’s Model 6517 and 6517A Electrometers
Specifications:
Channels Per Card: 10
Functions: Volts, Amps
Contact Configuration: Single pole, “break-beforemake” for signal HI input. Signal LO is common for all 10 channels and output. When a channel is off, signal HI is connected to signal LO. 6517B can also configure channels as voltage switches
Connector Type: Inputs: Triaxial. Outputs: Triaxial
Signal Level: 200V, 500mA, 10VA (resistive load)
Contact Life: >106 closures at maximum signal level; >107 closures at low signal levels
Contact Resistance: <1ω
Contact Potential: <200μV
Offset Current: <1pA (<30fA typical at 23°C, <60% RH)
Channel Isolation: >1013ω, <0.3pF
Input Isolation: >1010ω, <125pF (Input HI to Input LO)
Actuation Time: 2ms
Common Mode Voltage: <300V peak
Enviroment: Operating: 0° to 50°C up to 35°C at 70% R.H. Storage: –25° to 65°C
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 6522’s input connectors are 3-lug triax. The card can be software 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.
