Analysis Tools
PrecisionProbe provides many tools to allow you to know exactly what has
been characterized and what parameters have been improved by the innovative
software.
PrecisionProbe Wizard
PrecisionProbe provides an easy to follow guide with its wizard. The wizard
takes you step by step through the set up of the software and ensures that your
measurements are taken with the highest signal integrity.

Probe Correction
To maximize margins it is important to correct each probe identically and to ensure
the correction method is the same. The Probe Correction menu allows you to
change between Vout/Vin and Vout/Vsource. PrecisionProbe also allows for the
source impedance via s-parameter file or an estimate. This is important when
measuring Vout/Vsource to ensure a high level of accuracy as assuming an ideal
50 ohm environment can cause unwanted errors.

that you need
Bandwidth Control
Software such as PrecisionProbe can amplify high frequency noise when
correcting for the loss of a probe or cable. The high frequency noise can then
cause unwanted noise and inaccuracies. Bandwidth control allows you to remove
unwanted high frequency noise by providing a filter.
PrecisionProbe also provides the ability to control the amount of gain that is
applied to the signal. You can increase the amount of boosting which improves
risetimes but also increases noise, or you can decrease the amount of boosting
which decreases noise but degrades rise times.
