Measuring Signals
Using the Oscilloscope
as
a
Digital Voltmeter
-
With ground-refer-
enced cursors, you can also use the oscilloscope as a digital voltmeter for
measuring ordinary
DC
voltages (Figure 3-34).
Figure 3-34: Measuring
DC
Levels with Cursors
Measuring Time
with the
Graticule or Cursors
Make period or other time measurements between two points on a wave-
form using this basic procedure:
Step
1:
Display the signal on screen so that the first point you wish to
measure from is on screen.
Step
2:
In
NON-STORE
mode adjust the time base to place the other
horizontal point on screen and use the graticule lines to make the mea-
surement
-
or go to
STORE
mode and use the rest of this procedure.
Step
3:
In
STORE
mode, position a cursor on the first point of the
waveform with the cursor control.
Step 4:
Push the
CURSORS
knob in to select the other cursor and
position it on the second point. (On 4K or magnified displays an acquisi-
tion window indicator at the top of the display shows where the cursors
are relative to the entire record length.)
Step
5:
Note the
A
time (change or difference in time) readout in the
upper right corner of the display.
