TRACe:DATA
is a query, but you have to state a parameter in that case. The
parameter defines which data is returned (in this case, the data of trace 1; you
could also display a second trace whose data you could query with
TRACe:DATA
TRACE2
).
The trace data contains 1183 level values (one value for each pixel of the display).
The unit of the values is dBm. The values are shown in the message box of the
user interface.
You can copy the trace data from the message box and paste it into a text file,
spreadsheet etc. for further evaluation. (There are also SCPI commands that auto-
matically copy that data into a file, so you do not have to do that manually.)
Tip:
Logging commands with the . You can save all commands you have sent with
RsVisaTester into a log file (
.txt
file type) and reuse it later on.
To do so, turn on the "Write Log" feature and select a folder to save the file in
("Change Log File" menu item).

This was a short example of how to use SCPI commands to measure a signal.
Depending on your measurement task you can expand the succession of com-
mands as you like, write it into a script and automate a measurement.
