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 Main mode, use the large
Horizontal knob to change sweep speed and use the small
knob (
) to set the 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.
3 Press the Vernier softkey to turn on the time base vernier.
The Vernier softkey lets you change the sweep speed in
smaller increments with the time/division knob. The sweep
speed remains fully calibrated when Vernier is on. The value
is displayed in the status line at the top of the display.
When Vernier is turned off, the Horizontal sweep speed knob
changes the time base sweep speed in a 1-2-5 step sequence.
4 Note the setting of the Time Ref (time reference) softkey.
Time reference is the reference point on the display for
horizontal position (also called delay time). Time reference
can be set to one major division from the left or right edge, or
to the center of the display.
A small hollow triangle (
marks the position of the time reference. When horizontal
position is set to zero, the trigger point indicator ( )
overlays the time reference indicator.
Turning the Horizontal sweep speed knob will expand or
contract the waveform about the time reference point ( ).
Turning the horizontal position (
move the trigger point indicator ( ) to the left or right of the
time reference point ( ).
The time reference position sets the initial position of the
trigger event within acquisition memory and on the display,
with delay (horizontal position) set to 0. The horizontal
position setting sets the specific location of the trigger event
with respect to the time reference position. The time
reference setting affects the Zoom sweep as described in the
following ways:
