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.

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.
