Waveform Sample Rate:
The Waveform Sample Rate is the sample rate before the interpolators. Depending
on the Sample Rate Divider, this sample rate differs from the DAC Sample Rate
which is always in the range of 53.76 GSa/s … 65 GSa/s.
The dependency is:
DAC Sample Rate = Waveform Sample Rate * Sample Rate Divider
Waveform Granularity:
Depending on the Sample Rate Divider, the 256 sample wide output of the
sequencer is divided by 1, 2 or 4. This generates output vectors with a width of 256,
128 or 64 samples. This vector size is called waveform granularity and is the number
of samples per channel processed within one sync clock cycle.
