Description
|

|
Cache
|
Drivers may choose to always cache some instrument settings, never cache others, and optionally cache others, to avoid unecessary I/O to the instrument. If True, the driver caches optionally cached instrument settings.
|

|
DriverSetup
|
The driver setup string. It is either specified in the Configuration Store or passed in the OptionString parameter of the Initialize function. Driver setup is empty if the driver is not initialized.
|

|
InterchangeCheck
|
If True, the driver maintains a record of interchangeability warnings. If the driver does not support interchangeability checking, attempts to set InterchangeCheck to True return an error.
|

|
IoResourceDescriptor
|
The resource descriptor specifies the connection to a physical device. It is either specified in the Configuration Store or passed in the ResourceName parameter of the Initialize function. It is empty if the driver is not initialized.
|

|
LogicalName
|
Logical Name identifies a driver session in the Configuration Store. If Logical Name is not empty, the driver was initialized from information in the driver session. If it is empty, the driver was initialized without using the Configuration Store.
|

|
QueryInstrumentStatus
|
If True, the driver queries the instrument status at the end of each method or property that performs I/O to the instrument. If an error is reported, use ErrorQuery to retrieve error messages one at a time from the instrument.
|

|
RangeCheck
|
Drivers may choose to always validate some property/parameter values, never validate others, and optionally validate others, to avoid sending invalid commands to the instrument. If True, the driver performs optional validations.
|

|
RecordCoercions
|
If True, the driver keeps a list of the value coercions it makes for ViInt32 and ViReal64 attributes. If the driver does not support coercion recording, attempts to set RecordCoercions to True will return an error.
|

|
Simulate
|
If True, the driver does not perform I/O to the instrument, and returns simulated values for output parameters.
