2000-SCAN Keithley Switch Card New

In summary, the Keithley 2000-SCAN is a plug-in scanner / multiplexer card that installs in the rear option slot of the Keithley 2001 (7½-digit) and 2002 (8½-digit) High Performance Multimeters. The card converts the host DMM into a complete scan-and-measure system for up to ten measurement channels without adding a separate switching chassis, second instrument address, or external trigger cabling. Provides 10 switchable measurement channels routed through the host DMM. Suitable for general bench scan-and-measure applications such as multi-point voltage monitoring, resistor banks, and routine multi-channel characterization.

What is the 2000-SCAN used for?

The 2000-SCAN is used in multi-point precision measurement applications where a single Keithley 2001 or 2002 DMM serves as the measurement engine for several channels — for example, multi-resistor characterization, semiconductor parameter monitoring at multiple test points, temperature mapping across a thermal chamber, and multi-channel voltage logging. By routing the channels through the option slot rather than an external multiplexer, the host DMM, the scanner, and the trigger system are coordinated through a single IEEE-488 bus connection and a single SCPI programming context.

How does the 2000-SCAN extend the 2001 / 2002?

The 2001 and 2002 are bench precision DMMs already capable of multi-function measurement (DCV, ACV, DC current, AC current, ohms, frequency, period, temperature, peak, crest factor). Adding the 2000-SCAN extends those capabilities across 10 channels accessed under software control. The result is a measurement system that takes up the bench space of one DMM and is programmed as one instrument, but covers the channel count typically associated with a separate switching mainframe. The internal Trigger-Link coordinates scan timing with external instruments when needed.

Factual Grounding — Configuration and Compatibility

The 2000-SCAN is a plug-in card designed for the rear option slot of the Keithley 2001 and Keithley 2002 (including the MEM1 and MEM2 memory-extended variants). It is mutually exclusive with the other 2001/2002 option-slot cards: only one card occupies the option slot at a time. Available companion warranty service: 2000-SCAN-3Y-EW — 1-year factory warranty extended to 3 years from date of shipment. Available companion calibration service: C/2000-3Y-ISO — 3 ISO/IEC 17025-accredited calibrations within 3 years of purchase (not available in all countries).

Entity Authority — Keithley Switching Heritage

Keithley Instruments has supplied precision switching products to standards labs, semiconductor test groups, and metrology engineers since the 1980s. The 2000-SCAN, 2001-SCAN, and 2001-TCSCAN family represents the option-slot scanner approach that pairs directly with Keithley's bench precision DMMs — distinct from Keithley's larger 7000-series switching mainframes that are used when channel counts exceed what an option-slot card supports. For installed bases using the 2001 or 2002 as the precision engine, the option-slot card is the canonical multi-channel extension.

Available Calibration Service

C/2000-3Y-ISO — 3 (ISO-17025 accredited) calibrations within 3 years of purchase for Model 2000-SCAN (not available in all countries)

How the Card Fits the 2001 / 2002 Architecture

The 2001 and 2002 expose a rear option slot specifically for plug-in measurement extensions. The 2000-SCAN occupies that slot, integrates with the DMM's measurement chain, and is controlled by the same SCPI programming context as the host instrument. Scanning is initiated via the DMM's command set, with reading buffering supported by the host instrument's reading memory (8K standard; 32K with /MEM1 host; 128K with /MEM2 host). For applications that require more than 10 channels, multiple measurement channels can be combined across separate DMM stations linked by Trigger-Link, or the customer can move to a larger external switching mainframe — contact your Test Architect for system architecture guidance.
