Turning On/Off Traces
Press the corresponding Channel button (CH1–CH4) to turn on a trace. As
long as the acquisition system is not stopped, a waveform pattern appears
on the grid. To turn off a trace, press the Channel button again.
When a trace appears on the grid, the Channel descriptor box is color-coded
to match. This box always displays the current Vertical settings for the trace
and is labeled 1–4. The front panel Channel button also lights to show the
trace is on.
Math, Reference and Zoom Traces
In addition to the channel traces, you can view a zoom (close-up portion) of a
trace, a trace stored to the oscilloscope’s internal memory (REF1-REF5), or a
trace that displays the result of a math function applied to another trace (M).
Press the front panel
MATH button to turn on a math trace. Adjust the trace
by using the Math setup menu and front panel controls.
Use the
REF button to open the Reference Waveform menu and recall the
reference from memory.
Use the
ZOOM button to create zooms of active traces. If multiple traces
are on when you press ZOOM, zooms are created for each trace. Use the
Horizontal knobs to adjust zooms.

Replaying Traces
When acquisition is stopped, the Replay indicator
lights to show that there are records available in
memory to display—up to 2048 sweeps.
Turn the Replay knob to step back or forward one
sweep at a time, “replaying” the acquisition. Press the
knob to skip to the end of the acquisition.
The number of the sweep (out of 2048) is displayed at the far right of the
Acquisition status bar.
