Instrument Description Indicates whether the description is for an instrument or a module Warning, error fatal instrument, driver The amount of dynamic current in amps consumed by the device on each of the VXI backplane voltage lines. The amount of peak current in amps consumed by the device on each of the VXI backplane voltage lines. The number of ECL trigger lines concurrently input or sensed. The number of TTL trigger lines concurrently input or sensed. Identifies the keying class defined by the VXI specification. The module cooling as back pressure in mm/H2O Represents Module Cooling as air flow in liters/sec. Identifies the type of VXI address space needed by the instrument or module in addition to A16. The number of interrupt lines utilized by a device. The weight of the module in kilograms per slot occupied. The number of slots consumed. This type is used to store the amount of current in amps consumed by the device for each of the VXI backplane voltages. Used to specify the number of trigger concurrently input or sensed. Describes how the various instrument entities are connected.
