Figure 3–3: The Channel Readout
To select a channel, use the channel selection buttons on the right of the display.
These buttons labeled CH 1, CH 2, CH 3, CH 4, and MORE select a channel
and display it if its off. (The MORE button allows you to select internally stored
Math and Ref waveforms for display and manipulation.) The selected channel is
indicated by the lighting the LED above the button of the selected channel.
Do the following steps to first display and then remove waveforms from the
display:
1. Press CH 1, CH 2, CH 3, or CH 4 to turn on as many of these channels as
desired. The one you select last (or first if you only select one) becomes the
selected channel. Selecting a channel turns it on if it is not already on.
You do not use the channel selection buttons to select the trigger source.
Instead you select the trigger source in the Main Trigger menu or Delayed
Trigger menu.
2. Press WAVEFORM OFF to turn OFF the display of the selected channel
waveform. It will also remove from the display any automated measurements
being made on that waveform.
3. To select a math waveform you have created or a reference waveform you
have stored, press MORE and select the waveform from the More menu.
Press WAVEFORM OFF while the MORE button is lit to remove the
display of the waveform selected in the More menu.
