HP 83480A User Manual

Front Panel Measure Section
The HP 83480A and HP 54750A can perform several common
oscilloscope-type measurements, such as rise time, peak-to-peak voltage, and
overshoot. In addition to making these measurements on simple repetitive
pulse waveforms, the instrument can also make the measurement on more
complex signals, such as an eye diagram. In many cases, the measurement
algorithm for a two-level measurement, such as an eye diagram, is dierent
than the algorithm used when measuring a pulse waveform. In most cases,
the measurement is made on a color graded database. A basic discussion of
the process
of measurement
is found
in
Chapter
7.
Before making
signal measurements
,it
is important
the

correctly
congured

This is
typically
achieved
by
using
