To adjust the vertical position
Adjusting their vertical position lets you compare waveforms by aligning
them above one another or on top of each other.
When an input channel waveform is on:
•
Turn the vertical position knob to change the vertical position of the
waveform on the screen.
Notice that the ground reference symbol on the left side of the display
moves with the waveform.
• Push the vertical position knob to “zero” the ground reference (in other
words, move it to the center of the screen).
Notice that, as you adjust the vertical position, a message showing the
position of the ground reference relative to the center of the screen is
temporarily displayed in the lower left- hand corner of the screen.
To specify channel coupling
1 If the channel’s menu is not currently displayed, press the channel key
(
[1] , [2] , [3] , or [4] ).
2
In the Channel menu, press
Coupling
.
3
Continue pressing the
Coupling
softkey or turn the entry knob to
select between:
DC
Passes both DC and AC components of the input
waveform to the oscilloscope. See
Figure 16 .
You can quickly measure the DC component of the
waveform by simply noting its distance from the ground
symbol.
AC
Blocks the DC component of the input waveform and
passes the AC component. See
Figure 17 .
This lets you use greater sensitivity (amplitude/div
settings) to display the AC component of the waveform.
GND
The waveform is disconnected from the oscilloscope
input.
