depth up to 500M points, and the 4456CM/DM/EM provides a memory depth up to 200M points. The deep
memory means that it can keep high sample rate when capturing records for longer time, which can rebuild signal
waveform more accurately, bring better resolution between sampling points, and capture glitch or abnormal events
more probably. With the segment memory, you can selectively capture and save important signal activities and
avoid capturing invalid signal silence time.

Click the corresponding key of the required memory depth to set the memory depth.
Attention: When the 4456C/D/E is in a Sample mode, the max.memory depth can be set to 500M, and when it is
in other acquire mode, the max.memory depth can be set to 200M. When the 4456CM/DM/EM is in a Sample
mode, the max.memory depth can be set to 200M, and when it is in other acquire mode, the max.memory depth
can be set to 100M.
Click [Segment] menu key to open or close the segment mode. When the segment mode is switched on, the
memory will be divided into different segments according to different memory depths; when memory depth is set
to 1k, the memory can be divided into 131,072 segments maximally, which can be selected through the
Multipurpose b.
Attention: When the logic analyzer or bus is enabled, both the segment function and the [Segment] menu key will
