Displaying Signals
As soon as you enter the STORE mode the oscilloscope digitally acquires
the signal and actively displays it on the screen. Acquisition modes for
different sweep speeds are determined by default but they may be changed.
(Refer to Digitizing Signals, page 3-8.) The front panel controls that govern
the analog display in NON-STORE also govern the storage display. The
STORE mode, however, gives you the additional capabilities of digital pro
cessing, cursor measurements, and waveform storage and retrieval.

Selecting the Trigger Mode
Set the trigger mode to P-P AUTO for most routine displays. This mode
automatically adjusts the range of the trigger-level control for repetitive
signals above 20 Hz and automatically generates a sweep in the absence of
an adequate trigger signal.
There are many other ways to trigger a signal. Refer to the section entitled
Triggering on Signals, page 3-25, for a complete discussion.
Selecting the Horizontal Mode and Scale
Using the horizontal controls (Figure 3-2) you can display and horizontally
scale a signal applied to the oscilloscope. Use the SEC/DIV control to select
the horizontal scale factor and adjust the horizontal POSITION control as
necessary.
