Use the comman sequence
? ;
to query the return value (see example below).
Note:
It is not possible to run several programs simultaneously. If the command
PROGram[:SELected]:EXECute ...
is sent while a previously started program is
still executed, the analyzer generates a SCPI error
–100,"Command error..."
.
Tip: Executing batch files; command prompt
When executing batch scripts or other DOS applications, the analyzer does not display
any DOS windows; the screen is left for the vector network analyzer (VNA) application.
The same applies to the Windows NT command prompt (
cmd.exe
). To access the
command prompt, proceed as follows:
●
Create a batch file (e.g.
Start_cmd.bat
) containing the command line
start cmd.exe
and store the file to
C:\Winnt\system32
.
●
Execute the batch file:
PROG:EXEC 'C:\winnt\system32\Start_cmd.bat'
The command prompt window is displayed in front of the VNA application. You can
also open several command prompt windows simultaneously.
Setting parameters:
<AppName>
String variable containing the name and path of an application
program to be executed or of a file to be opened. The path can
be defined as an absolute path (e.g. 'c:\...') or relative to the cur-
rent directory (
Blanks in the
<AppName>
can be used to separate the applica-
tion name from (optional) parameters.
Example:
PROGram:SELected:NAME PROG
Select general program execution.
PROGram:SELected:EXECute 'Exit42.bat'
Run batch script
Exit42.bat
.
PROGram:SELected:WAIT?
Lock command execution and manual control of the analyzer
until the batch job has finished. This is required for
PROGram:SELected:RETVal?
Get the return value. The answer is ... 42.
Usage:
Setting only
PROGram[:SELected]:INIMessage
<IniFile>[, <SendValue>]
Writes a message
<SendValue>
into the preferences (
*.ini
) file specified by
<IniFile>
. The message is entered into the
[MESSAGE]
section using the fixed key
Send
; the value for the fixed key
Receive
is set to an empty string.
The query reads the value associated with the fixed key
Receive
from the
[MESSAGE]
section of the preferences file specified by
<IniFile>
. If no value exists
for that key, the query returns an empty string.
