Performance Issues Using A MXI Connection
When using a MXI-3 connection to control the PXI chassis, you must run
the MXI Optimization Application prior to using the NI RF signal
generator. By default, this application runs automatically when Windows
starts. Using a MXI connection without running this application may result
in a
