Number of Points. This bezel menu sets the number of points of the waveform to be
created or the length of Edit Memory. The point can be set to a value in the follow-
ing range:
2 to 65,536 (AFG3021 and AFG3022)
2 to 131,072 (AFG3101/AFG3102 and AFG3251/AFG3252)
If a waveform is already written to Edit Memory and Number of Points is set to a
value smaller than the number of points in that waveform, then the data for the
points starting at that value plus one will be lost. For example, if Number of Points
is set to 500 in the state where a waveform with 1000 points has been written to
Edit Memory, the waveform data for points 1 to 500 will remain without change
but the data from point 501 will be lost.
If a waveform is already written to Edit Memory and Number of Points is set to a
value greater than the number of points in that waveform, then the data for the
points starting at that value plus one to the point identified by the Number of
Points will be set to the zero level. For example, if Number of Points is set to 1500
in the state where a waveform with 1000 points has been written to Edit Memory,
the waveform data for points 1 to 1000 will remain without change and the data
from point 1001 to point 1500 will be set to zero level. See Figure 2-3 for an exam-
ple using the Number of Points parameter.
