The Command Editor is an excellent tool for learning low level
programming of the 2074. Invoke the Command Editor from the
System menu at the top of the screen. Dialog box, as shown in
Figure 4-57 will pop up. If you press the Download button, the
function call in the Command field will be sent to the instrument.
Figure 4-57, the Command Editor
Low-level SCPI commands and queries can be directly sent to the
2074 from the Command field and the instrument will respond to
queries in the Response field. The command editor is very useful
while developing your own application. Build your confidence or test
various commands using the command editor. This way you can
assure that commands or syntax that you use in your application
will behave exactly the same way as it responds to the editor
commands. A complete list of SCPI commands is available in
Chapter 5.
The Log File is very useful for programmers that do not wish to
spend a lot of time on manuals. When you use ArbConnection,
every time you click on a button or change parameter, the
command is logged in the same format as should be used in
external applications. Figure 4-58 shows an example of a log file
and a set of SCPI commands as resulted from some changes made
on ArbConnection panels. You can set up the 2074 from
ArbConnection to the desired configuration, log the commands in
the log file and then copy and paste to your application without any
modifications. Of course, this is true for simple commands that do
not involve file download but, on the other hand, this is a great tool
to get you started with SCPI programming.
