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:
●
A trace can be created and handled without being displayed.
●
Traces are referenced by trace names. The active trace of a channel is often refer-
enced by the channel suffix.
●
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.
●
In remote control, it is possible to display the same trace in several diagrams.
●
The analyzer provides several commands allowing a smooth transition between
remote and manual control.
// 1. One channel, two traces, one diagram
// Reset the instrument, creating the default trace Trc1 in channel 1.
// The default measured quantity is the forward transmission S-parameter S21.
// The default format is dB Mag.
*RST
// Create a second trace in channel 1, assign the format Phase,
// and display the new trace in the same diagram.
// the trace becomes the active trace but is not displayed
CALCulate1:PARameter:SDEFine 'Trc2', 'S21'
// the trace is referenced by the channel suffix 1
CALCulate1:FORMat PHASe
// display the second trace, numbering it the second trace in diagram no. 1
DISPlay:WINDow1:TRACe2:FEED 'Trc2'
// Check the result on the local screen
// Go to local
SYSTem:DISPlay:UPDate ONCE
// 2. One channel, two traces, two diagrams
// Create a second diagram, assign Trc2 to the new area, and remove it
// from the first area.
DISPlay:WINDow2:STATe ON
DISPlay:WINDow2:TRACe2:FEED 'Trc2'
// Trc2 is now displayed in both diagrams
DISPlay:WINDow1:TRACe2:DELete
// Check the result on the local screen
// Go to local
SYSTem:DISPlay:UPDate ONCE
