To set up the Horizontal time base
1 Press the [Menu/Zoom] key (or [Main/Delayed] key on some oscilloscopes) in the
Horizontal section of the front panel.
The Horizontal Menu lets you select the horizontal mode (Normal, Zoom, XY, or Roll), and
set the time base fine adjustment and time reference.
The current sample rate is displayed above the Fine and Time Ref softkeys.
Normal mode
1 Press the Normal softkey to select Normal horizontal mode.
Normal horizontal mode is the normal viewing mode for the oscilloscope. When the
oscilloscope is stopped, you can use the Horizontal knobs to pan and zoom the
waveform.
2 Turn the large knob (time/division) in the Horizontal section and notice the change it
makes to the status line.
When the oscilloscope is running in Normal mode, use the large Horizontal knob
marked to change sweep speed and use the small knob marked to set the
delay time (horizontal position). When the oscilloscope is stopped, use these knobs to
pan and zoom your waveform. The sweep speed (seconds/division) value is displayed
in the status line.
