Figure EĆ10: Waveform Memory Configuration
The waveform data length can be any multiple of 8 points, from a minimum of
64 points to a maximum of 256K points. The total number of waveform data
points that can be used in a single sequence file is 256K.
Data Length. Generally, outputting high precision (high S/N ratio) waveforms
requires an adequate number of data points.
For example, when outputting triangular waveforms, about 8000 points are
needed to minimize the jaggedness of the waveform. That is why the AWG2021
uses a DAC with a resolution of about 4000 (12 bits) for the vertical amplitude.
Figure E-11 shows the relationship between the triangular wave resolution and
the number of data points.
