IQ Data Streaming (IQ data)—Adds inline signal processing to augment RTG target creation. Some use cases include:

• Creating additional targets
• Adding radar pulse measurements
• Creating clutter simulation
• Real-time signal monitoring

Target Streaming (Target configurations)—Sends RTG target configurations directly from the coprocessor to the RTG VST. Some use cases include:

• Dynamic target configuration creation on the FPGA
• Target configurations sourced from another device
• Transfer of target configurations faster than is possible from a non-real-time windows host

Coprocessor Hardware Components

The coprocessor harness is designed to work with NI FPGA-based processing hardware. You must place the coprocessor in the same PXIe chassis where the RTG is located. IQ data streaming shares data with the RTG through a cable connected to the VST and the coprocessor front panel. Target streaming shares data with the RTG using peer-to-peer (P2P) communication on the PXI backplane. RTG supports the following coprocessor harness hardware:

• PXIe-6594 (Not compatible with the PXIe-5842 VST)
• PXIe-7903

Coprocessor Software Components

You can use the Coprocessor Harness with the following:

RTG Coprocessor Template—Includes a LabVIEW FPGA project and VIs that provide code to stream both data and target configurations. Make a copy of these files into a new directory when you start a custom coprocessor project.

Host Classes—Includes an interface and a base class that enable communication between the RTG and the coprocessor.

• RTG coprocessor link host
• RTG coprocessor target streaming host
