Vertical Controls
1
Press the desired channel key.
2
In the Channel Menu, press the
Coupling
softkey to select the input channel
coupling:
•
DC
— DC coupling is useful for viewing waveforms as low as 0 Hz that do not
have large DC offsets.
•
AC
— AC coupling is useful for viewing waveforms with large DC offsets.
AC coupling places a 10 Hz high-pass filter in series with the input waveform
that removes any DC offset voltage from the waveform.
Note that Channel Coupling is independent of Trigger Coupling. To change trigger
coupling see
"To select the trigger coupling"
To specify bandwidth limiting
1
Press the desired channel key.
2
In the Channel Menu, press the
BW Limit
softkey to enable or disable bandwidth
limiting.
When bandwidth limit is on, the maximum bandwidth for the channel is
approximately 20 MHz. For waveforms with frequencies below this, turning
bandwidth limit on removes unwanted high frequency noise from the waveform.
The bandwidth limit also limits the trigger signal path of any channel that has
BW
Limit
turned on.
To change the vertical scale knob's coarse/fine adjustment setting
1
Push the channel's vertical scale knob (or press the channel key and then the
Fine
softkey in the Channel Menu) to toggle between fine and coarse
adjustment of the vertical scale.
TIP
If the channel is DC coupled, you can quickly measure the DC component of the signal by
simply noting its distance from the ground symbol.
If the channel is AC coupled, the DC component of the signal is removed, allowing you to use
greater sensitivity to display the AC component of the signal.
