Hello,
I'm a user of Agilent DSO81204B with memory option. I would like to
capture as many segments as possible in the segmented acquisition mode.
Is there a method or table to get the maximum available segments
for a given acquisition points and sampling rate?
I checked the number of maximum segments for a given points.
It is likely that sampling rate also relates to the available number of
segments. In case of 10 Gsample/sec and 20,000 points, 2048 segments
were maximum. However, I got 1024 segments for 2 Gsample/sec
and 20,000 points.
Thanks,
Tsutomu Tsuda

The maximum number of samples per segment is typically the max memory per channel divided by the number of segments rounded up to the next power of 2.
For the DSO80000 Series scopes, the maximum segment size is 1 M for sample rates ≥5GSa/sec. The memory is doubled when in 2 channel mode for sample rates ≥4 GSa/sec. Due to overhead in the acquisition, the maximum samples per segment is reduced when you use a large number of segments >2048 in DSO80000 Series
