Reduces the overhead introduced by this measurement by not copying and storing the data in RFmx. In this mode IQ data needs to be retrieved using RFmxInstr Fetch Raw IQ VI instead of RFmxSpecAn IQ Fetch Data VI. RFmxInstr Fetch Raw IQ directly fetches the data from the hardware.

The following list describes the limitations of using this mode,

  • No other measurements can be enabled along with this IQ measurement.
  • You must fetch the IQ data before initiating another RFmx measurement because the data is not stored in RFmx.
