NI 5441 IQ Rate Component

NI Signal Generator

NI 5441
IQ Rate Component

The IQ rate component holds off the data from the output engine so that a new sample is only output once every Total_OSP_Interpolation Sample clocks where:

Total_OSP_Interpolation = FIR Interpolation × CIC Interpolation

Note  The Total_OSP_Interpolation does not include the DAC interpolation.

NI-FGEN calculates the FIR Interpolation, CIC Interpolation, and the Sample Rate based on the specified IQ Rate.

Tip  To override the FIR interpolation rate and/or CIC interpolation rate calculated by NI-FGEN, you can set the FIR Interpolation Factor and/or the CIC Interpolation Factor properties.
