The graphical user interface elements
8. The Help Everywhere icon indicates
when the Help Everywhere function
is enabled to display information on
oscilloscope settings when you open a
menu.
9. The trigger level icon shows the trigger
level of the active (selected) waveform.
Use the Trigger
Level knob to adjust
the trigger level. The trigger level value
is shown in the horizontal and trigger
readouts at the bottom of the screen.
The oscilloscope shows two trigger level
icons when you are triggering on a runt
waveform. The trigger level knob only
controls the lower trigger threshold level
when in runt trigger mode. Use the
Trigger Menu to set both trigger levels.
10. The Time and Date readout shows the
oscilloscope clock setting. (See page 11,
Changing the date and time .)
11. The Horizontal and Trigger readouts
show Trigger, horizontal scale, sample
rate, trigger delay time, and record length
information.
The Trigger readouts shows the
trigger source, slope, and the
trigger threshold level. The readout
also shows the measured signal
frequency. The trigger readouts
for other trigger types show other
values. The image shows the
readouts for an
Edge trigger.
The horizontal position/scale
readouts show the horizontal scale
setting (time per major horizontal
graticule division; adjust with the
Horizontal Scale knob) and the
sample rate (number of samples per
second).
