Specifications
Introduction
Only values with tolerances or limits are guar-
anteed data. Values without tolerances are in-
formative data, without guarantee.
Measurement
Functions
Refer to page 8-55 for uncertainty informa-
tion.
Inputs A and B can be swapped in all modes
except Rise Time and Fall Time.
Display: All measurements are displayed
with a large main parameter value and smaller
auxiliary parameter values (with less
resolution). Some measurements are only
available as auxiliary parameters.
