Scanner Configuration for Models 2000-SCAN
and 2001-SCAN
Optional Multiplexer Cards
Creating a self-contained multipoint measure-
ment 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 appli-
cations involving more than 10 measurement
points, the 2000 is com patible with Keithley’s
Series 7000 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 compensation
