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.General Settings:Trigger IdentifierSpecifies which trigger mechanism to use. In VXI systems, for example, you can choose between software triggers and hardware triggers on a specific trigger line. The default is Software.GPIB Settings:Primary AddressReturns the primary address of the GPIB device used by the given session.GPIB Settings:Secondary AddressReturns the secondary address of the GPIB device used by the given session. If the device does not have a secondary address, the value of this property is 65535 (0xFFFF).Interface Information:Interface Number of ParentReturns the board number of the parent device.VXI/VME Settings:Asserted VXI Trigger LinesReturns the current state of the VXI trigger lines. This property returns a bit vector with bits 0-9 corresponding to TTL0 through ECL1.VXI/VME Settings:Asserted VXI/VME Interrupt LinesReturns the current state of the VXI/VME interrupt lines. This property returns a bit vector with bits 0-6 corresponding to interrupt lines 1-7.VXI/VME Settings:Mainframe Logical AddressReturns the lowest logical address in the mainframe in which the device resides.VXI/VME Settings:Supported VXI Trigger LinesReturns which VXI trigger lines this implementation supports. This property returns a bit vector with bits 0-9 corresponding to TTL0 through ECL1.VXI/VME Settings:VXI/VME System Failure StateReturns the current state of the VXI/VME SYSFAIL (SYStem FAILure) backplane line.
