Step
4:
Connect the probe tip to the signal source.
Step
5:
Wait several seconds for the input-coupling capacitor to charge
to the DC level of the signal source.
Step
6:
Set the input coupling switch to
AC.
Position the AC signal
within the graticule area.
Displaying
a
simple, repetitive signal is one of the most common tasks
encountered when using an oscilloscope. To properly display a signal you
must make the appropriate control settings in four different sections of the
front panel:
CRT Display
Vertical
Horizontal
Trigger
These control sections are arranged left to right across the front panel of the
2232
Digital Storage Oscilloscope.
Presetting the Controls
It
is
often helpful to preset the front panel controls to get
a
sweep on the
screen before you try to apply a signal. With
a
simple "trace" on screen you
can adjust the display intensity and focus before you make any other set-
tings.
If you are unfamiliar with oscilloscopes you may want to begin with the basic
analog setup given in Start Up, page
1-4.
In addition, the following sections
describe the basic controls and a general approach to setting them:
Selecting the Display Mode
(STOREINON-STORE)
Selecting the Trigger Mode
Selecting the Horizontal Mode and Scale
Selecting the Vertical Mode and Scale
Setting the Display Intensity and Focus
Finding "Lost" Displays
Selecting the Display Mode (STOREINON-STORE)
Toggle the
STOREINON-STORE
button to display signals in either the
digital
(STORE)
or analog
(NON-STORE)
mode. You may find it helpful to
set up the signal display in the analog mode first before switching to the
STORE
mode.
