Selecting Channels
In Detail
3Ć108
To select a channel:
Pressing CH 1, CH 2, CH 3 (AUX 1 on the TDS 620), or CH 4 (AUX 2 on the
TDS 620) turns the channel on if it is not already on.
You do not use the channel selection buttons when triggering. Instead select
the trigger source in the Main Trigger menu or Delayed Trigger menu.
Removing Waveforms From the Display
The WAVEFORM OFF button turns OFF the display of the selected channel
waveform. It will also remove from the display any automated measurements
being made on that waveform.
When you turn off a waveform, the oscilloscope automatically selects the next
highest priority waveform. Figure 3-52 shows how the oscilloscope prioritizes
waveforms.

)

Figure 3-52: Waveform Selection Priority
If you are turning off more than one waveform and you start by turning off a
channel waveform, all channels will be turned off before going to the MORE
waveforms. If you start by turning off the MORE waveforms, all the MORE
waveforms will be turned off before going to the channel waveforms.
If you turn off a channel that is a trigger source, it continues to be the trigger
source even though the waveform is not displayed.
