Superior measurement speed and integrity

   In addition to the wide range of measurement functions and capabilities common to all Series 2000 DMMs, the Keithley Model 2001 has many other advantages for test system builders. While other DMMs may claim to offer 71⁄2-digit resolution, they typically must average multiple readings to achieve their specified resolution, which slows the reading rate significantly. In contrast, the Keithley Model 2001¿s true 71⁄2-digit resolution is based on a 28-bit A-to-D converter, so no averaging is needed to discern smaller changes. This high resolution also provides greater dynamic range, so it¿s possible to measure from 1µV to 20V on a single range and avoid range-shift errors.

Unique measurement capabilities

   Unlike the Model 2000 or 2010, the Model 2001 offers the ability to make peak spikes measurements without the need for a separate oscilloscope. Its internal peak detector can catch 1µs spikes, such as power supply spikes and transients, AC line power surges, and short-duration drop outs on components, as well as up to 1MHz for repetitive signals. The Model 2001 can automatically display and store the highest value, or display the maximum and minimum values of spikes. Similarly, no oscilloscope is required to determine if the crest factor¿the ratio of peak value to rms values¿of an AC signal is acceptable to ensure measurement accuracy, because the Model 2001 measures AC crest factor directly. While some DMMs will calculate average AC from the RMS value, these calculations apply only to sine wave inputs. With the Model 2001, it¿s easy to measure AC peak value, average, and true rms directly to characterize the signal completely. This capability is ideal for AC circuit design or test, and to verifying test voltages specified only in averages.
