IviUpconverterBase Capability Group
The IviUpconverterBase capability group supports basic upconverter operation. You can use the VIs and properties in the IviUpconverterBase capability group to configure and access IF input frequency and attenuation as well as RF output frequency and gain. This capability group also defines VIs for using an external local oscillator (LO).
This specification defines an IF input repeated capability to accommodate devices that offer multiple IF inputs. Many devices, however, offer only a single IF input. The following figure presents the basic aspects of a single-input upconverter.
The figure illustrates an upconverter that has a single IF or I/Q input feeding the front-end elements of the device. The frequency translation section includes a mixer, filter, and amplifier followed by an RF gain stage. Depending upon the design of the upconverter, the order in which these elements appears may vary.
Some upconverters offer multiple IF inputs along with multiple RF outputs. This specification does not dictate whether the RF outputs are dedicated to specific IF inputs or whether they are shared amongst the multiple IF inputs. You can use a repeated capability naming scheme that indicates whether or not RF outputs are associated with specific IF inputs.
