Operating Basics
Select an Input Channel
After you have connected probes to the desired inputs, you will want to select
an input channel and set the parameters for that channel. To select a channel,
do the following:
1. Press one of the channel buttons to display the associated input menu and
to turn the input on.
2. Coupling is DC by default. Select AC coupling if you want to observe a small
AC signal that rides on a DC signal. When AC coupling is active, the
1~ icon
will be visible in the lower left portion of the display screen.
NOTE. Autoset can affect how coupling functions. For more information, read
about the Autoset feature. (See page 29, Display an Unknown Signal with Autoset
or AutoRange™.)
3. Press the function button to select Input Options and select the desired
attenuation and bandwidth settings. Read more about attenuation and
bandwidth settings. (See page 38,
Acquire Waveforms .)
Assign Position and Scale
to Multiple Channels
If the channel button is illuminated, the horizontal and vertical Position and Scale
buttons are assigned to the indicated channel.
To assign the Position and Scale buttons to multiple channels, do the following:
1. Press and hold the Ch 1 button.
2. Press another one or more channel buttons in sequence.
3. Release the Ch 1 button.
All pressed buttons are now illuminated. The Position and Scale buttons now
apply to all active channels.
To deactivate this feature, press a single channel button.
