Selecting Groups and Channels
3–120
TLS 216 User Manual
NOTE . Turning a group off does not make its channels available for including in
other groups. Turning off a group that includes a channel providing a trigger
source does not turn that channel off as a trigger source. Turning off a group
does remove any automated measurements of channels in that group.
When you turn off the selected waveform group using the GROUP OFF button,
the logic scope automatically selects the nearest higher priority waveform group.
For instance, turning of Group 6 selects Group 5, and so on. Table 3–5 lists in
order how the logic scope prioritizes waveforms. (Turning the selected group off
using the Group Display Mode menu does not cause a new group to be selected,
rather the logic scope leaves the group you turned off selected.)
There are two orders of priority shown in Table 3–5. The one the logic scope
uses depends on the type of group you turn off first. If you turn off a live group,
pressing GROUP OFF again turns off the live group with the next highest
priority as listed in Table 3–5. You can continue this process until all live groups
are off.
Turning off a reference group first reverses this process. If you start by turning
off a REF group, all the REF groups will be turned off before going to the live
groups.
