This property is read/write until the first time you call VISA Enable Event on a session. Thereafter, it is read only. The default is 50.General Settings:Resource ClassReturns the resource class of the resource string used to open the given session. For example, if the resource string for a given session is COM1 or ASRL1::INSTR, this property returns INSTR, regardless of the class of the I/O control.General Settings:Resource Lock StateReturns the current locking state of the resource associated with the given session. The resource can be unlocked, locked with an exclusive lock, or locked with a shared lock. The default is Unlocked.General Settings:Resource NameReturns the unique identifier for a resource.General Settings:Timeout ValueSpecifies the minimum timeout value, in milliseconds, to use when accessing the device. Note that the actual timeout that VISA returns may be higher than the one requested. The default is 2000.General Settings:User DataSpecifies a data value for the private use of an application. The VISA implementation stores this value in a per-session location, so that user data on other sessions does not affect the user data on this session. VISA does not use this property for any purpose.Interface Information:Interface DescriptionSpecifies human-readable text that describes the given interface. Note: Use the value of this property for display purposes only and not for programmatic decisions. The value can change between VISA implementations and/or revisions.Interface Information:Interface NumberReturns the board number for the given interface.Interface Information:Interface TypeSpecifies the interface type of the given session.Version Information:Resource Manufacturer IdentificationReturns a value that corresponds to the VXI manufacturer ID of the manufacturer that created the VISA implementation.Version Information:Resource Manufacturer NameReturns the name of the manufacturer that created the implementation. This is not related to the device manufacturer attributes. Note: Use the value of this property for display purposes only and not for programmatic decisions. The value can change between VISA implementations and/or revisions.Version Information:Version of ImplementationReturns the version of a given implementation. This value is defined by the individual manufacturer and increments with each new revision. The format of the value has the upper 12 bits as the major number of the version, the next lower 12 bits as the minor number of the version, and the lowest 8 bits as the sub-minor number of the version.Version Information:Version of SpecificationReturns the value that uniquely identifies the version of the VISA specification to which the implementation complies. The format of the value has the upper 12 bits as the major number of the version, the next lower 12 bits as the minor number of the version, and the lowest 8 bits as the sub-minor number of the version.Register Based Settings:Destination Increment CountSpecifies the number of elements by which to increment the destination address on block move operations. Valid values include 0 and 1. The default is 1. If this property is set to 0, VISA Move Out X operations always read from the same element, essentially treating the destination as a FIFO register.Register Based Settings:Source Increment CountSpecifies the number of elements by which to increment the source address on block move operations. Valid values include 0 and 1. The default is 1. If this property is set to 0, VISA Move In X operations always read from the same element, essentially treating the source as a FIFO register.Register Based Settings:Window AccessReturns whether the current session has a mapped window, and if so, whether the window allows direct pointer dereferences.Register Based Settings:Window Base AddressReturns the base interface address to which this window maps. If the Window Access property is Not Mapped, the value of this property is undefined.Register Based Settings:Window SizeReturns the size of the region mapped to this window. If the Window Access property is Not Mapped, the value of this property is undefined.
