Getting access to shared resources
On some instruments multiple applications share the same
hardware resources. For that reason SmartClass™ Fiber
instruments have the simple paradigm: the application which is
visible on the GUI always has access to the shared resources.
Regarding remote control, an application may not provide full
functionality if it is not the currently visible application. In order
to make sure the remote controlled application has full
functionality, one should make the application visible by using
the commands in the following table.
Notes: Applications that are not currently visible will return
-221,“Settings conflict” when setting a Setup that affects
shared resources, Results will return an invalid value
9.91E37 (NAN), and most of the Extended Remote
Commands will return -100,“Command error”.
Query the numerical setting range in the setup
The suffixes :MINV and :MAXV return the minimal and maximal
allowed values:
e.g. :SYSTEM:DISP:BRGH:MINV? returns the value 10 and
:SYSTEM:DISP:BRGH:MAXV? the value 100.
Command Purpose
:APPM:LIST? Provides a list of all application IDs separated by commas
:SYSTEM:APP:ID:VSBL
<app_ID>
Makes the application corresponding to the application ID visible
:SYSTEM:APP:ID:VSBL? Retrieves the ID of the currently visible application
