Using the Waveform Display Knobs
Symbol/Field Description
1 Vertical Volts/Div. Makes the waveform bigger or smaller vertically in relation to its ground reference. Specified in
volts/division or amps/division on the y axis. On outputs with multiple ranges, when Knob Con-
trol is selected in the Scope Range Property window, adjusting the vertical gain will automatically
select lower measurement ranges for better resolution. If the vertical gain causes the traceto be
out of view, arrow symbols will indicatethe direction of the trace .
2 Vertical Offset Moves the ground reference of the trace up or down in relation to the horizontal center line of the
grid. The offset popup that appears in the upper rightcorner of the display shows howfar the
ground reference of the selected traceis above or belowthe horizontal center line of the grid.
Positivevalues indicate thatthe center line is above the ground reference. Negative values indicate
thatthe center line is below the ground reference.
3 Trigger Level Moves the trigger level up and down when a voltageor current level is the trigger source. The
trigger level is identified by the symbol. If the trigger level is out of view, an arrow
indicates the direction of the trigger level.
Push the Trigger Level knob to auto-scale the traces on the display. This will trigger a new
measurement.
4 Horizontal Time/Div Stretches or shrinks the waveform horizontally around the horizontal offset reference. Specified in
time/division on the x axis. Applies to ALL traces.
5 Horizontal Offset Moves the waveform to the right or leftof the horizontal offset reference. Thetrigger pointis
indicated by the solid arrow.
