Basic Operation
Horizontal Position Control
When the oscilloscope is running, this control lets you set the
acquisition window relative to the trigger point. When the
oscilloscope is stopped, you can turn this knob to pan
through the data horizontally. This lets you see the captured
waveform before the trigger or after the trigger.
The trigger position is marked with the indicator “ ” at the top
of the graticule and also in the waveform record icon at the
top of the screen.
The small inverted triangle () is the time reference indicator.
When you change the horizontal scale, the waveforms
contract or expand about this point.
Press the horizontal position control knob key to set the time
delay to zero, and the trigger position indicator ( ) overlays
the time reference indicator().
Note: The horizontal position control is unavailable when
X-Y horizontal mode is selected.
Horizontal Scale Control
Use the horizontal scale control to adjust the time base. The
scale expands or contracts around the center of the screen.
The horizontal scale factor can be set in a 1-2-5 sequence.
