Keithley 2001-SCAN 10-Ch Scanner Card

The Keithley 2001-SCAN 10-Channel Scanner Card expands the measurement capabilities of compatible Keithley digital multimeters by enabling automated, multi-point signal acquisition across ten independent channels. Operating as a multiplexer, the card allows sequential scanning and data routing to the host DMM with minimal latency, supporting both 2-pole and 4-pole signal configurations. This approach eliminates the need for external switching hardware and streamlines test procedures requiring repeated measurements across distributed test points.
