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 dis-
cussed 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 differ-
ent traces in a diagram.
4. The analyzer provides several commands allowing a smooth transition between
remote and manual control.
