DIGITAL MULTIMETERS & SYSTEMS A Greater Measure of Confidence www.keithley.com 1.888.KEITHLEY (U.S. only) 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 Model 2001 and 8½-digit Model 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 instru - ments have the same look, feel, and response . T rue 7½- (or 8½-) Digit r esolution While other DMMs may claim 7½- or 8½-digit resolution, they must aver - age multiple readings to extend their resolution . The resolution speci- fications 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 1µV to 20V on a single range, thus avoiding range-shift errors and delays bui lt-In sc anner (Multiplexer) op tions 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 pro- vided by the 2002 make it an excellent choice for production test, design verifi- cation, and metrology applications where high accuracy is c ritical . H igh ac curacy aC V 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 increas - es 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 . A pplications involving vibration, servo, guidance, shock, and control systems often require accu - rate low frequency ACV measurements . The 2001 and 2002 maintain very good accuracy (better than 0 .1 %) down to 1Hz . The wide bandwidth of these DMMs allows for accurate measurements of high frequency AC signals without the need for a special AC meter . Both the 2001 and 2002 feature TRMS AC, average AC, peak AC, AC+DC, and crest factor measurement capability for a wide variety of

applications

H igh sp eed for High Throughput In applications where high throughput is critical, both the 2001 and 2002 provide more than 2000 readings per second at 4½-digit resolution At 7½ digits, the 2002 maintains full rated accuracy at reading rates up to 44/second on DCV and ohms . H igh sp eed, High Precision re sistance Measurements The Model 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 resis - tances that can result from fast test handlers . A built-in open-lead detection circuit also eliminates many production test problems . fa st, fl exible Triggering Trigger latency—the delay between trigger and measurement—is often a barrier to higher throughput A lso, variability in latency can complicate predicting measurement timing . The 2001 and 2002 trigger is less than 2µs±1µs, which is much faster than typical system DMMs .

T rigger-Link combines six independent software selectable trigger lines on a single connector for simple, direct control over all instruments in a system . sp ot Trends with the ba r-Graph Display The ability to track reading trends around a target value easily can be just as important as the abso - lute readings . A unique bar-graph display function in the 2001 and 2002 indicates data as a percent - age of the selected range from ±0 .0 1% to ±100% . Whether adjusting about zero or any other desired value, this display can replace a nulling differential voltmeter . C apture sp ikes Down to 1µs Both the 2001 and 2002 have internal peak detectors that can catch 1µs spikes such as power supply spikes and transients, AC line power surges, and short-duration dropouts on components These peak detectors operate up to 1MHz for repetitive signals or down to 1µs for single spikes, so there is no need for a separate scope The DMMs can automatically display and store the highest value or display the maximum and minimum values of spikes . bu ilt-in fe atures and Capabilities The 2001 and 2002 offer many built-in measurements that are typically unavailable in instruments of this type, including in-circuit current, temperature with thermocouples or RTDs, and peak spikes F our separate outputs linked to limits simplify configuring the DMMs for use in binning operations .

Other DMMs typically perform AC measurements for signals without excessive crest factor—the ratio of peak value to rms values However, when crest factor rises, measurements may not meet specs With a 2001 or 2002, there is no need for an oscilloscope to determine if the crest factor is acceptable—the DMM measures it directly W hile some DMMs calculate average AC from the rms value, these calculations apply only to sine wave inputs The 2001 and 2002 measure peak value, average and true rms directly to obtain a complete characterization of the signal This capability makes these DMMs ideal for AC circuit design or test applications and for verifying test voltages specified only in averages W hen measuring AC or digital signals, frequency is critical . The 2001 and 2002 accurately meas- ure frequency up to 15MHz . Accurate triggering on the signal is critical to measure frequency reliably The frequency counters in the 2001 and 2002 have a fully adjustable trigger level for good measurements of noisy signals . Mu ltiple Measurement Display The 2001 and 2002 can display DC and AC volts and the AC frequency from a single measure - ment connection simultaneously Several other multiple-measurement displays are available, including crest factor and bar graph By meas- uring sequentially and displaying simultaneously, the 2001/2002 operates as if three different meters are working together op tion sl ot Extends DMM Performance An option slot in the back of the 2001 and 2002 opens the door to a wide range of measurement capabilities Choose a 10-channel general-pur- pose scanner card or a 9-channel thermocouple scanner card to make measurements on multiple test points or devices This can eliminate the need for a separate scanner and significantly reduce programming and setup time aCCEssorI E s aVaIl ablE TEsT lE a D s a ND Prob Es 5805 K elvin Probes, 0 .9 m (3ft) 5805-12 K elvin Probes, 3 .6 m (12ft) 5808 L ow Cost, Single Pin, Kelvin Probes 5809 L ow Cost, Kelvin Clip Lead Set 8502 M icro-DIN to 6 BNCs Adapter Box with 8501-1 Cable 8530 C entronics Adapter 8605 H igh Performance 2-Wire Modular Test Leads 8606 H igh Performance Modular Probe Kit 8610 L ow Thermal Shorting Plug 8680 R TD Probe Adapter 8681 L ow Cost RTD CablEs/ aDa PTE rs 7007-1 S hielded GPIB Cable, 1m (3 .3 f t) 7007-2 S hielded GPIB Cable, 2m (6 .6 f 8501-1 T rigger-Link Cable, 1m (3 .3 f 8501-2 T rigger Link Cable, 2m (6 .6 f 8502 T rigger Link Adapter Box 8610 L ow Thermal Shorting Plug 8620 -Wire DMM Shorting Plug raCK MouNT K ITs 4288-1 S ingle Fixed Rack Mount Kit 4288-4 S ide-by-Side Rack Mount Kit GPIb INTE rfaCEs KPCI-488LPA I EEE-488 Interface Controller for the PCI Bus KUSB-488B I EEE-488 USB-to-GPIB Interface Adapter High resolution, high accuracy DMMs High resolution, high accuracy DMMs
