BOTH - The licen
se is in the application module and the license from another
application module of the same type has already been transferred to the scope.
NEITHER -Thel
icense is neither in the application module nor in the scope's
internal memory. (In this situation, the license must have been transferred to a
different oscilloscope.)
NONE - There is no application module in the slot.
Examples
APPLication:LICENSE:SLOT1:LOCation? might return SCOPE, indicating
that the license is active internally.
APPLication:LICENSE:SLOT<x>:TRANSFER (No Query Form)
You can use this command to transfer a license from a physical application module
to an internal memory location within the oscilloscope, and to transfer it back.
Once a license has been transferred to an internal location, the application that it
enables can be used without the physical application module being present;the
physical application module can be removed, thus freeing up a slot. However,
the license then needs to be transferred back to the physical application module
in order to use the license with another instrument.
After licenses have been transferred, the oscilloscope power must be cycled in
order to enable/disable the features affected by the module. Applications modules
must only be installed and removed when the oscilloscope power is off.
CAUTION. Applications modules must only be installed and removed when the
oscilloscope power is off.
< x> can be slot number 1-4 (1-2 for MDO3000 models).
NOTE. In order to use many of the advanced oscilloscope features, you must
purchase an application module that contains a license. A license turns on a
feature that is already present in the firmware. The module can be inserted
into any of the four application module slots in the oscilloscope (two for the
MDO3000 series). While only four of the more than twelve physical a pplication
modules available can be supported at one time (or two for the MDO3000 series),
more than this number o f applications can be used simultaneously: a license
can be transferred from the physical application module to an internal location
within the oscilloscope.
Conditions
If the license currently resides in the physical application module and the license
does not also reside in the scope, it is transferred to the scope and the license is no
longer in the module.

If the license c
urrently resides in the scope and the license does not also reside in
the module, the license is transferred from the scope to the module.
If the applica
tion module slot is empty, an error event is posted to the event queue
so indicating and no operation is performed.
If the licen
se resides in both the scope and the module, an error event is posted to
the event queue so indicating and no operation is performed.
If the licen
se resides in neither the scope nor the module, an error event is posted
to the event queue so indicating and no operation is performed.

This query returns the application license type of the module that is currently
inserted in the specified application module slot. If there is no application
module in the slot,
NONE is returned. < x> can be slot number 1-4 (1-2 for
MDO3000 models).

ICENSE:SLOT<x>:TYPe?
Related Commands
APPLication:LICENSE:SLOT<x>:TRANSFER,
APPLication:LICENSE:SLOT<x>:LOCation?
Examples
APPLication:MODule:SLOT1:TYPe? might return DPO4AUTO, indicating that
the DPO4AUTO license is installed in slot 1.
APPLication:TYPe
This command sets or returns the application type. These are the applications
available when the front panel "Test" button is pressed. The query form willreturn
NONe if none of the supported test application modules are installed.
Attempting to set the application type to a type with no application module
installed will result in a settings conflict error event.
NOTE. The Video Picture features are standard on MDO3000 and
MDO4000C series models. They require the
DPO4VID application module for
use with MSO/DPO4000B, MDO4000 and MDO4000B models.
NOTE. The Act on Event features are standard on all models. The Limit/Mask and
Power features are optional for all models.
Conditions
Video Picture commands are available for MDO3000 and MDO4000C series
models. They require the DPO4VID application module for use with
MSO/DPO4000B, MDO4000 and MDO4000B models
The Limit/Mask and Power features require the MDO3LMT or MDO3PWR
application modules for the MDO3000 series models, or the DPO4LMT or
DPO4PWR application modules for the MDO4000/B/C series.
