To Adjust The Horizontal (Time/Div) Scale; To Adjust The Horizontal Delay (Position) - Agilent Technologies 7000B Series User Manual

To adjust the horizontal (time/div) scale

1 Turn the large horizontal scale (sweep speed) knob marked
The  symbol at the top of the display indicates the time reference point.
Note that the horizontal scale knob has a different purpose in the Zoom
display. See
The horizontal scale knob works (in the Normal time mode) while
acquisitions are running or when they are stopped. When running,
adjusting the horizontal scale knob changes the sample rate. When
stopped, adjusting the horizontal scale knob lets you zoom into acquired
data. See
page 64.

To adjust the horizontal delay (position)

1 Turn the horizontal delay (position) knob (
The delay knob moves the normal sweep horizontally, and it pauses at
0.00 s, mimicking a mechanical detent.
Changing the delay time moves the sweep horizontally and indicates how
far the trigger point (solid inverted triangle) is from the time reference
point (hollow inverted triangle ). These reference points are indicated
along the top of the display grid.
The previous figure shows the trigger point with the delay time set to
400 s. The delay time number tells you how far the time reference point
is located from the trigger point. When delay time is set to zero, the delay
time indicator overlays the time reference indicator.
All events displayed left of the trigger point happened before the trigger
occurred. These events are called pre- trigger information, and they show
events that led up to the trigger point.
