Oscilloscope Overview and Set Up
Front Panel
Front panel controls duplicate functionality available through the touch
screen and are described here only briefly.
Knobs on the front panel function one way if turned and another if
pushed like a button. The first label describes the knob’s “turn” action,
the second label its “push” action. Actions performed from the front
panel always apply to the active trace.
Many buttons light to show the active traces and functions.
Trigger Controls
The front panel Level knob changes the trigger threshold level (V). The
number is shown on the Trigger descriptor box. Pushing the knob sets
the trigger level to the 50% point of the input signal.
Setup opens the Trigger setup dialog. Press it again to close the dialog.
The READY indicator is lit when the trigger is armed and ready. TRIG'D is
lit momentarily when a trigger occurs.
Auto sets Auto mode, which triggers the oscilloscope after a set time,
even if the trigger conditions are not met.
Normal sets Normal mode, which triggers the oscilloscope each time a
signal is present that meets the trigger conditions.
Single sets Single trigger mode. The first press readies the oscilloscope
to trigger. The second press arms and triggers the oscilloscope once
(single-shot acquisition) when the input signal meets the trigger
conditions.
Stop prevents the scope from triggering on a signal. If you boot up the
instrument with the trigger in Stop mode, a "No trace available"
message is shown. Press the Auto button to display a trace.
Horizontal Controls
Turn the Delay knob to change the Trigger Delay value (S). Push the
knob to reset Delay to zero.
If the trace source is an input channel, turn the Horizontal Adjust knob to
set the Time/division (S) of the oscilloscope acquisition system. The
value is shown on the Timebase descriptor box. When using this
control, the oscilloscope allocates memory as needed to maintain the
highest sample rate possible for the timebase setting. If the trace source is a zoom, memory or math function, turn
the knob to change the horizontal scale of the trace, effectively "zooming" in or out. The value is shown on the
corresponding descriptor box. Push the knob to adjust scale in variable (single) increments; push it again to return to
1, 2, 5, 10-step increments.
