Several traces with different channel settings...
Programming task:
Create three channels with 3, 1 and 2 traces, respectively, and
display the traces in two diagrams.
Important remote control features for this program example
The following command sequence illustrates the structure of the remote commands
discussed in section Basic Remote Control Concepts. In particular it shows that:
1. Channels are always referenced by a channel suffix.
2. Traces are referenced by trace names. The active trace of a channel is often refer-
enced by the channel suffix.
3. Diagrams are referenced by a window suffix
<Wnd>
. An additional suffix
<WndTr>
in the
DISPlay:WINDow<Wnd>:TRACe<WndTr>...
commands numbers the dif-
ferent traces in a diagram.
4. The analyzer provides several commands allowing a smooth transition between
remote and manual control.
