Selecting Traces By Touch; Figure 2 15: The Waveform Major Menu With The Knob Menu - Tektronix 11801C User Manual

Example 2: Managing Multiple Traces
Selecting Traces by
Touch
2 22
To select a different trace simply touch the desired trace. An outline box
indicates your potential selection. If only one trace passes through that
outlined area when you withdraw your finger, it will become the selected
trace. If several traces pass through the outlined area, repeatedly touching
the same area will select successive traces.
Step 11: Touch the traces to change selections. Try touching an area
with one trace, and an area where both appear together.
The Waveform major menu shows status of the selected trace (see Figure
2 15). The Vertical Desc selector shows the trace expression of the selected
trace.
Step 12: Press the WAVEFORM major menu button in the MENUS
column and observe (don't touch) the Vertical Desc selector.
If the selected trace displays mainframe channel 1 then the Vertical Desc
selector will show M1. (Fast is a trace parameter that is described in
Example 3.) Channels can be combined in a single trace, for example
M1+M3, as you will see in Example 3.
The Remove/Clr Trace n selector of the Knob menu also shows the expres
sion of the selected trace. (It also indicates that the Main time base is used.)

Figure 2 15: The Waveform Major Menu with the Knob Menu

The number n in the Remove/Clr Trace n selector is the trace number
assigned by the 11801C when the trace is created. It should not be con
fused with the trace expression. Trace numbers range from 1 through 8. This
selector always shows the number of the selected trace.
Step 13: Select each trace by touch, and observe the Vertical Desc
and Remove/Clr Trace n selectors and the sampling head lights.
