Increasing Measurement Accuracy
and Time-Interval Measurement
What you'll nd in this chapter
This chapter tells you how to obtain the highest accuracy available from the instrument. Though the
examples refer to the HP 83480A and HP 54750A, most of the principles apply to any instrument.
The discussion is divided into four sections. The rst section describes various methods for making
time-interval measurements and the pros and cons of each. The second section introduces the concept
of statistical analysis of time intervals. The third section explores errors in time-interval measurements
that
are
not
related to
the time
base accurac
y,
including
the
response
of
the
instrument's
vertical
channels
and
the
eect of
probes.
This
chapter
also
examines
the
distortions
introduced
b

vertical
channels,
the
probes,
and

and
it
