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 only 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. The front panels of both instruments have the same look,
• High-speed function and range
changing
• Broad range of built-in
measurement functions
• Multiple measurement display
feel, and response, so the learning curve is reduced dramatically.
True 71⁄2- (or 81⁄2-) Digit Resolution
While other DMMs may claim 7½-or 8½-digit resolution,
those instruments 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
• Flexible option slot design
• Nanovolt Preamp option (Model
1801)
• IEEE-488.2 and SCPI compatible
• Model 2002 has HP 3458A
emulation mode
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 and to
avoid range-shift errors.
Applications
The 2001 is well suited to general-purpose measurements that
require high resolution and accuracy. With the addition of a
plug-in scanner card, it becomes a complete scan and measure
system for applications involving up to ten measurement
points. The additional resolution and measurement ranges

where high accuracy is critical.
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 not only increases
the accuracy at almost any voltage level, but 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 input signals.
Applications involving vibration, servo, guidance, shock, and control systems often
require accurate 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 highfrequency AC signals without the need for a special AC meter. Both the 2001 and
2002 feature TRMS AC, Average AC, Peak AC, and AC+DC measurement capability
for a wide variety of applications.
High Speed for High Throughput
I
n 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.

High Speed,High Precision Resistance Measurement
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 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
trigger in less than 2µs ±1µs, which is 100–1000 times faster than other DMMs.
The unique Trigger-Link feature included in the Model 2001 and 2002 and a growing number of
other Keithley test and measurement products can be used to coordinate the operation of two or
more instruments. Trigger-Link combines six independent software selectable trigger lines on a single connector for simple, direct control over all instruments in a system.
Spot Trends with the Bar-Graph Display
The ability to track reading trends around a target value easily can be just as important as the absolute readings. A unique bar-graph display function in the 2001 and 2002 indicates data as a percentage of the selected range from ±0.01% to ±100%. Whether adjusting about zero or any other desired
value, this display can replace a nulling differential voltmeter.
Capture Spikes 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’s
no need for a separate scope. The DMMs will automatically display and store the highest value or
QQZQ
display the maximum and minimum values of spikes.
Built-in Features 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.
QZQQ
QZZQ
Four separate outputs linked to limits simplify configuring the DMMs for use in binning operations.
Built-in AC crest factor measurement helps ensure the accuracy of AC measurements. 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’s no need for an oscilloscope to determine if the crest factor is acceptable—the DMM
measures it directly.
While some DMMs will calculate average AC from the rms value, these calculations apply only to
sine wave inputs. The 2001 and 2002 allow measuring 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.
When measuring AC or digital signals, frequency is critical. The 2001 and 2002 accurately measure
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.
Multiple Measurement Display
The 2001 and 2002 can simultaneously display DC and AC volts and the AC frequency from a single
measurement connection . Several other multiple-measurement displays are available, including
crest factor and bar graph. By measuring sequentially and displaying simultaneously, the 2001/2002
operate as if three different meters are working together.
Option Slot 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-purpose 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. The Model 1801 Nanovolt
Preamp extends the performance of either DMM by extending the low-level
measurement ranges and amplifies the voltage sensitivity dramatically.
