The Keithley 2000-SCAN is a 10-channel scanner card that expands the multiplexing capabilities of compatible Keithley digital multimeters. It enables efficient multipoint test and measurement systems by consolidating multiple test points into a single instrument, reducing external equipment requirements and simplifying test execution through integrated triggering, timing, and processing functions.
