The system calibration utility is included in the NI mmWave Reference Project. This utility calibrates the system by measuring in-phase/quadrature (I/Q) impairments for each channel. To use this utility, the mmWave Transceiver System must be configured as a transceiver or a receiver.
|Transceiver||Receiver and transmitter|
You must recalibrate the system if you exchange any of the following components:
The measured I/Q impairments are stored on the PXIe-3620 module.
When using the reference FPGA design and host code provided by the NI mmWave Reference Project, the measured I/Q impairments are retrieved from the device by the Open VI and used by the Configure VI to correct the system.
