Automation Command and Query Reference Manual - Control Reference

LabelsPosition

String

Any number of characters

Range

Sets / Queries the horizontal position of the label attached to the acquisition trace Cx. The unit of
measurement is the unit of the horizontal scale. The measurement is made from the trigger point.
Note that this control is a string, not a numeric value. This allows multiple labels to be positioned, as
shown in the example below.

LabelsText

String

Any number of characters

Range

Persist3DQuality

Enum

This control only has an effect when Persisted is true and Persistence3D is true. It controls whether
the 3D view is shown as a wire frame (which can be monochrome or color graded), a solid (also can
be monochrome or color graded), or a shaded solid (always monochrome). For WireFrame or Solid,
if monochrome the brightness increases with height; if color graded the color changes from puple to
red with height. "Shaded" present the solid as if it were lit from the upper left.

Description

Values

Shaded

Solid

WireFrame

PersistDotJoined

Bool

If this control is false (the default state), then samples are put into the persistence map as dots. The
advantage of that is that any lit pixel in the pmap actually corresponds to a sample of the data taken at
that time. The disadvantage of dots is that there is no way to associate a dot with any other dot; there
is no history of which dots were part of the same acquisition. If this control is set to true, then each
acquisition draws lines into the persistence map that connect the dots at the sample positions. Clearly
the advantage of that is that it is now possible to see if some outlier samples were all part of the same
acquisition, or not. The disadvantage is that lit points in the persistence map no longer correspond to
actual samples, the lines between the samples are also lit. If the persistence map is going to be
analyzed it is probably preferable to leave Dot Joined off so that only actual samples are considered in
the analysis.
If there are very few points in a persistence map, there may columns with no points, that is, there are
gaps horizontally between points. Dot Joined will connect them starting with the last trace, and for all
subsequence traces accumulated. The action of turning on or off Dot Joined clears the accumulated
persistence map.

Description

Persisted

Bool

Sets/Queries the persisted state of the waveform. If the Display.LockPersistence control is set to
'AllLocked' then the persisted state of all displayed waveforms will be the same. If the
Display.LockPersistence control is set to 'PerTrace' then the persisted state of each waveform may be
independently controlled.
