The System and
Command Editor
ArbConnection requires certain conditions to work well with the
PXA125. For example, The computer you are using must be
connected to the PXI chassis through a known and well-defined
communication link, such as, MXI3. Not only that the instrument must
be connected but also, software and registers must be set properly for
the generator to function properly. It is also possible that your
computer is running smoothly but the PXA125 has problems
communicating with your computer. The System and Command
Editor dialog box has all the tools needed to make sure that the
PXA125 is connected properly and that it responds correctly to
machine commands.
Invoke the System and Command Editor from the System command
at the top of the screen. Dialog box, as shown in Figure 3-13 will pop
up. There are three main functions that you can execute using this
dialog box: Set your communication link, reset and test your
communication with the PXA125 and, last but no least, send SCPI
commands to the instrument and see an immediate response.
Description of the various elements of this dialog box is given below.
Communication The Communication group lets you select the proper communication
link for connecting the PXA125 to the computer. In general,
