IviDigitizerDownconversion Extension Group
The IviDigitizerDownconversion extension group supports digitizers with the ability to translate frequency or downconvert in hardware. You can use this extension group to return only the frequency-translated data at the potentially lower sample rate. For example, the digitizer in a synthetic instrument system can acquire an IF signal and return I/Q data.
When you enable downconversion, the digitizer Read and Fetch VIs return interleaved data, and thus, twice as many points. Enabling the Sample Rate property specifies the downconverted sample rate, not the ADC sample rate.
