IviDownconverter Class Driver Overview
This instrument driver provides programming support for the IviDownconverter Class. The IviDownconverter class is designed to support the typical downconverter as well as common extended functionality found in more complex instruments. The IviDownconverter class driver conceptualizes a downconverter as an instrument that can convert RF input frequency signals to IF output frequency signals suitable for processing by a downstream system component, such as a digitizer.
The IviDownconverter class driver divides instrument capabilities into an IviDownconverterBase capability group and several extension capabiliy groups. You can use the IviDownconverterBase capability group to configure a downconverter for basic input and output filtering and gain/attenuation stages.
In addition, the IviDownconverter class defines extended capabilities for downconverters that support different styles of sweeping the RF input and provide more precise control of signal routing through the various downconverter stages.
Use this driver to develop programs that are independent of a particular downconverter. You can use this class driver with any downconverter that has an IVI instrument specific driver that is compliant with the IviDownconverter class. The IviDownconverter class driver accesses the specific driver for your instrument using the configuration information you supply in MAX.
