Identifies the type of error. Abstract type used to describe hardware entities. Derived types include Instrument Description, UUT Description, Test Station Description, etc. This collector permits listing any subcomponents of the subject Hardware Item. Unbounded set of elements describing and identifying each subcomponent. At a minimum, there must be a description and a Part Number. This collector permits listing the parents of the Hardware Item. Unbounded set of elements describing the Hardware Items into which this Hardware Item can be used as a component. TODO: Need a better name for singular/plural firmware The driver type is specified by providing a type that derives from the "Driver" abstract type. The derived type includes any informaiton that is specific to that driver type. The schema includes derived types for serveral different driver types. Identifies any dependencies. Identifies the platform requirements for using this driver. The control language is specified by provideing a type that derives from the "ControlLanguage" abstract type. Any software tool that comes with the item, e.g., Calibration Utility, Soft Front Panel, etc. Identifies any dependencies. Name of the configuration option. Configuration options are values the user can modify that persist after a power-cycle. Keyword-value pair for identifying manufacturer item defaults. Identifies the support equipment needed for running calibration. The calibration procedure. Specifies how often calibration needs to be executed. List of errors associated with the item. Warning, error fatal item, driver Netlist describing how all the ports in the item are wired together. In the simplest scenario, the capability ports get wired to Resource ports and the resource ports get wired to the item ports. Abstract type for control language identification Derived types include SCPI and Register Specifies that the item can be controlled using SCPI commands Specifies that the item is register based Specifies that the item can be controled using some generic control language Abstract type for drivers. Derived types include VPP, IVI, IVI-C, IVI-COM, etc. VXI plug and play driver IVI driver - includes structure for specifying whether the driver is an IVI-C or IVI-COM driver Name of IVI class(es) provided by this driver IVI-C driver IVI-COM driver ProgID used to instantiate the driver class. COM driver Win32 DLL based driver LabView driver Matlab driver Base type for sub-components of a hardware item Allows multiple identical items to be described with a single element in an instance document. Starting index for the items. Number fo identical items Specifies the value to increment by when calculating the value with which the replacement character is replaced. Allows for defining items where paired items have different characteristics. Defaults to 1. Character replaced with calculated index when repeated items are expanded. Index used to identify the resource. Describes how the various item entities are connected. Non-power interfaces. Test Station cooling requirements. Used to identify the minimum/maximum version Used to indicate whether the version speciifed is the minum or maximum version supported. Details needed to interface with this trigger signal Free text to give details of this trigger signal Details of the signal that will generate the trigger Name should be descriptive of what this signal does Base type for trigger properties Properties if trigger comes from an analog signal Properties if trigger comes from a digital signal Properties if the trigger is intiated by a SW call Properties if the trigger is a LXI LAN trigger Describes the analog voltage needed for the trigger Need to have edgeDetection or levelDetection or both Direction and type are important to know what interfaces this trigger can be routed to/from. Created TriggerPortType to allow capturing of LAN and SW trigger types. Collector element used to group list of capabilities and the mapping of capabilities to ports Base type used to describe capabilities Describes how capabilities are mapped to resource ports
