Acquiring and Displaying Waveforms

TDS 500D, TDS 600B, & TDS 700D User Manual
HORIZONTAL controls are ignored in DPO XY and XYZ.
XY format is a dot-only display, although it can have persistence. The Vector
style selection has no effect when you select XY format.
Several modes/features are unavailable when DPO mode is selected:
FastFrame, Limit Testing, Extended Acquisition, and Zoom modes
Envelope, Average, Hi Res, and Single Acquisition Sequence acquisition
modes and Autosave mode
Intensified time base
Record lengths longer than 500 samples
Interpolation (equivalent time sampling is used instead)
Vectors when in equivalent time mode (waveforms are displayed as Dots
instead). (To determine under what conditions the oscilloscope normally
interpolates or uses equivalent time, see Selecting Repetitive Sampling on
page 3–36.)

Measurements on channels when in DPO XY or XYZ
AMI triggers are allowed, but display invalid isolated one trailing edges
Plot hardcopy formats
Horizontal positioning is ignored
