Waveform display concepts
Waveform display overview
This instrument includes a flexible, customizable display that lets you control how waveforms appear. The figure shows how the display
features fit into the overall instrument operation.
The display shows analog, digital, math, reference and bus waveforms. The waveforms include channel markers and trigger source and
level indicators.
W
aveform preview mode
The waveform preview attempts to show what the next acquisition will look like when the acquisition is delayed due to slow triggers or
long acquisition duration, or when the acquisitions have stopped. Waveform preview recalculates math waveforms, but does not represent
changes in trigger levels, trigger modes, or different acquisition modes.
Horizontal position and the horizontal reference point
The time value you set for horizontal position is measured from the trigger point to the horizontal reference point. This is not the same as
the time value from the trigger point to the start of the waveform record, unless you set the horizontal reference to 0%. See the next figure.
