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.
While 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.
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.
