bottom line shows the time from the T symbol to the expansion point icon
(adjust with the Horizontal Position knob). Use horizontal position to insert
added delay between when the trigger occurs and when you actually capture
thedata.Insertanegativetimetocapture more pretrigger information. With
Delay Mode off, the bottom line shows the time location of the trigger within
the acquisition, as a percentage.
12. The Timing Resolution readout shows the timing resolution of the digital
channels. Timing resolution is the time between samples. It is the reciprocal
of the digital sample rate. When the MagniVu control is on, “MagniVu”
appears in the readout.
13. Measurement readouts show the selected measurements
. You can select up to
eight measurements to display at one time. A
