5.3.2 Incremental signal display
In the basic function "Incremental signal display" the incremental signals A/B are displayed on the
oscilloscope and the signal parameters as bar charts.
The tolerances of the A/B signals can be checked here. A number of settings are available to
adjust the display to the current testing situation.

To select the function, double-click "Incremental signal display".
The "Incremental signal display" is a digital storage oscilloscope that can display the relevant
incremental signals and standard tolerances. The sinusoidal signals A and B can be displayed
as a circle function (x-y graph) or as sine-cosine diagram (y-t graph).
The display type is selected in the setup menu . The diagrams can be saved and printed.
Note
The oscilloscope function is sufficient for most standard tests. Fast signal changes (error
spikes, noise, etc.) might not be detected!
For this purpose additional testing equipment, such as a PWM 9 and a digital oscilloscope
is required.
