Scanner Configuration for Models 2000-SCAN and 2001-SCAN

Optional Multiplexer Cards

Creating a self-contained multipoint measurement solution is as

simple as plugging a scanner card into the option slot on the

2000’s back panel. This ap proach eliminates the complexities

of triggering, timing, and processing issues and helps reduce

test time significantly. For applications involving more than 10

measurement points, the 2000 is com patible with Keithley’s

switch matrices and cards.

Model 2000-SCAN Scanner Card

• Ten analog input channels (2-pole)

• Configurable as 4-pole, 5-channel

Model 2001-SCAN Scanner Card

• Ten analog input channels

• Two channels of 2-pole, high-speed, solid-state switching

Model 2001-TCSCAN Thermocouple Scanner Card

• Nine analog input channels

• Built-in temperature reference for thermo couple cold-junction
