Example 2: Grouping Waveforms
The TLS 216 Logic Scope displays and controls waveforms as groups of one or
more waveforms, with eight groups available for display at the same time. Once
grouped, you can display waveforms as analog waveforms, or as digital levels on
a bus (BusForms
t
), or as a timing diagram, depending on which display mode
best helps you analyze your digital circuit.
Do the following tasks to learn to how to define and display groups of
waveforms, to adjust the waveforms as a group, and to choose a display mode.
Display a Waveform Group
Do the following steps to define and display a waveform group.
1. If you are not continuing from the previous example, follow the instructions
on page 1–7 under the heading “Setting Up for the Examples.”
2. If you have changed any control settings since resetting the logic scope, reset
it now: press Save/Recall SETUP
➞
Recall Factory Setup (main)
➞
OK
Confirm Factory Init (side). Press SET LEVEL TO 50%.
3. Use the vertical POSITION knob to move GROUP 1 to the top of the
display.
4. Press SHIFT, and then press GROUP 6. There are several changes to the
display:
H
The vertical readout indicates that a new group (Group 6) has been
created containing the first available channel (that is, the lowest
numbered channel not already belonging to a group—in this case,
Channel 2).
H
The Group 1 readout no longer appears in the vertical readout. The
vertical readout displays the group labels in two pages: Group 1 through
Group 4 on page one, and Group 5 through Group 8 on page two. To
force the readout to display group labels in either of these two pages,
select a group in the desired page.
H
The logic scope lights the LED below Group 6 to indicate it is selected.
It lights the same LED when Group 2 is selected. You can always
determine the selected group by looking at the vertical readout. It always
displays the selected group with its label in reverse video.
H
The logic scope displays each group (up to the sixth displayed) in a
different color to help you distinguish one group from another (the group
