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 8-9 for uncertainty information.
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 aux-
iliary parameter values (with less resolution).
Some measurements are only available as aux-
iliary parameters.
