Understanding the Analysis Charts
PrecisionProbe comes with many analysis charts that make understanding the characterization and correction very easy
and provide insight that is unique to Keysight oscilloscopes.
The Summary Chart
The summary chart shows the frequency response of the
corrected probe or Vout (notice how flat the response is).
The chart also shows the transfer function (TF) that is
applied to the signal.
Probe Input Impedance
Knowing the impedance profile of the probe allows you to
estimate the loading of the probe system. PrecisionProbe
allows for you to characterize the impedance profile, along
with quickly determining the capacitance, impedance and
inductance. Markers allow for easy viewing of the capaci-
tance and inductance at each frequency

Probe Correction Filter
The probe correction filter simply shows the filter that is
being applied to adjust for the probe. This filter is designed
to ensure the signal stays perfectly flat.
