Abstract
An apparatus and method for constraining amplitude range parameters associated with the acquisition and display of signals under test.
Claims20
Apparatus, comprising:
- a signal acquisition device, for constraining a signal under test (SUT) according to an amplitude range parameter and generating therefrom a stream of acquired samples;
- and
- a controller, for generating a display signal suitable for use by a display device and including constrained SUT waveform imagery visually cooperating with amplitude segment delineators;
- said controller, in a first mode of operation, adapting a number of amplitude segment delineators in response to said amplitude range parameter.

A user interface adapted for use in a signal acquisition device, said signal acquisition device producing a display signal including a waveform layer and a grid layer, comprising:
- a first user manipulable region for enabling user selection of an amplitude range acquisition parameter to adapt thereby a waveform representing an acquired signal under test (SUT);
- and
- a second user manipulable region for enabling user selection of an amplitude display parameter to adapt thereby an amplitude portion of a display grid intended to be superimposed over said waveform.
An oscilloscope, comprising:
- signal acquisition circuitry for acquiring a plurality of samples of at least one signal under test (SUT) in response to at least one range control signal;
- signal display circuitry for displaying at least a portion of said acquired samples and a corresponding display grid;
- and
- a controller, for modifying said at least one range control in response to a first user command, and for modifying said display grid in response to a second user command;
- wherein:
- said display grid modification comprises at least one of modifying a number of amplitude grid lines and selecting a units per amplitude grid line.
