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 capacitance and inductance at
each frequency.
