This schema defines the information associated with a Test Station. List of non power facilities requirements Non-power interfaces. Cooling requirements. List of location and address of instruments. Where the component is located physically. The address used to communicate with the component. The station's main controller. Installed OS(s). List of available video capabilities. List of available audio capabilities. Processor information. x86, PPC, SPARC, etc. Probably should be an enum or inherited type. Pentium M, Power PC, etc. Clock speed. List of available system peripherals. List of installed software, includes station selftest. Test Station Paths are signal paths through test station. This could include wiring and switching. Begin and end node. This could be one section of wire or the begin and end of a path composed of multiple wires and/or switches. The signal losses associated with this path. Path loss at specified frequency. Delay time of signal through this path (electrical length) Voltage Standing Wave Ratio (VSWR) associated with this path. Characteristic impedance of this path (only applicable if entire path described has same characteristic impedance). Abstract type for instrument drivers. 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 Abstract type for control language identification Abstract type for identifying the bus used to communicate with the instrument 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. Describes how the various instrument entities are connected. A short (one or two sentence) textual description of the specification A rigorous (mathematical) description of how the specification is defined and measured Conditions under which this specification is measured. The minimum value of the specification. Two-sided specs (with a min and max value) will always have this. One-sided specs may not. The maximum value of the specification. Two-sided specs (with a min and max value) will always have this. One-sided specs may not. Supplies graphical data for specifications that vary with other parameters. Some specs are only available in graphical format. Supplying a bitmap of the graph is one way to satisfy this requirement; the other is to ask the vendor to include all the data, but that would lose important annotations from the graph itself. Any additional information that is necessary to clarify the specification. This includes information that is contained in footnotes of the datasheet Instrument options that are required for this spec to be valid Instrument options that make this spec invalid
