2001 7½-Digit High Performance Multimeter 2002 8½-Digit High Performance Multimeter Datasheet Key Features • True 7½- (2001) or 8½-digit (2002) resolution • Exceptional measurement integrity with high speed • High speed function and range changing • Broad range of built-in measurement functions • Multiple measurement display • Built-in 10 channel scanner option • GPIB interface • HP3458A emulation mode (2002) True 7½- (or 8½-) Digit Resolution While other DMMs may claim 7½- or 8½-digit resolution, they must average multiple readings to extend their resolution. The resolution specifications of the 2001 and 2002 are based on a 28-bit A/D converter that provides the resolution needed to discern smaller changes. This higher resolution also provides greater dynamic range, making it possible to measure from 1 µV to 20 V on a single range, thus avoiding range-shift errors and delays. DMM users whose applications demand exceptional resolution, accuracy, and sensitivity combined with high throughput now have two attractive alternatives to high priced, high end DMMs. Keithley’s 7½-digit 2001 and 8½-digit 2002 High Performance Digital Multimeters not only deliver performance specifications usually associated with instruments that cost thousands more, but they also offer a broad range of functions not typically available from DMMs. The 2002 is based on the same superior measurement technology as the 2001, and the front panels of both instruments have the same look, feel, and response. Built-In Scanner (Multiplexer) Options With the addition of a plug-in scanner card, the 2001 or 2002 becomes a complete scan and measure system for applications involving up to ten measurement points. The additional resolution and measurement ranges provided by the 2002 make it an excellent choice for production test, design verification, and metrology applications where

2001 7½-Digit High Performance Multimeter 2002 8½-Digit High Performance Multimeter High Accuracy ACV Measurements A patented circuit design makes the 2001 and 2002’s AC measurements several times more accurate than competitive DMMs. In this circuit, the signal bypasses the prime error-contributing section of conventional rms converters. This increases the accuracy at almost any voltage level, and also increases sensitivity down to a guaranteed 1% of the selected range, compared to 5–10% for most other DMMs. The result is highly accurate measurements over a broad range of inputs....

High Speed, High Precision Resistance Measurements The 2002 uses a unique single-phase method for 4-wire ohms measurements. This makes it twice as fast for a given power line cycle rate. This also eliminates errors due to changing lead resistances that can result from fast test handlers. A built-in open-lead detection circuit also eliminates many production test problems. Fast, Flexible Triggering Trigger latency—the delay between trigger and measurement—is often a barrier to higher throughput. Also, variability in latency can complicate predicting measurement timing. The 2001 and 2002...
