Maximum number of averages that can
be supported
Number of samples required: Lines x 2.56 + lines x 2.56(#avg -1) x (1 -%overlap)
Max number of samples per configuration: 32768
Max number of averages = ((32768 / (lines x 2.56)) - 1) / (1 -%overlap) + 1)
The following table shows the maximum number of averages versus the number of lines and
percent overlap for non-trigger point.
The following table shows the maximum number of averages versus the number of lines and
percent overlap for pre-trigger point.
Signal detection RMS, Peak, Peak-Peak
Configuration downloading Route mode configuration downloads to Flash memory
Live mode configuration downloads to RAM
Note: You can reduce number of average or increase percent overlap to reduce amount of
memory used.
