An application requires using seven complex waveforms with the
following sizes: 500; 1,000; 1,000; 5,000; 10,000; 250; and
130 samples with the OSP block enabled and the Data Processing
Mode property set to Complex or the
NIFGEN_ATTR_OSP_DATA_PROCESSING_MODE
attribute set to
NIFGEN_VAL_OSP_COMPLEX
. Additionally, the signal generator is
configured for Arbitrary Sequence mode and Continuous trigger mode
with 100 segments in a sequence list. The following table shows all the
numbers used to determine the total memory stored in the onboard
memory: 78,720 bytes.
