Segmented memory: A smart and efficient way to
capture waveforms
Acquisition memory size is an essential oscilloscope specification
because it determines the amount of data you can capture in a
single acquisition. In general, longer memory is better. However,
no memory is always long enough to capture all the signals you
need, especially when capturing infrequent anomalies, data
bursts, or multiple serial bus packets. Segmented memory
acquisition lets you selectively capture and store important signal
activity without capturing unimportant signal idle time with the
time stamp of each segment relative to the first trigger event.
Segmented memory comes standard in the 4000 X-Series.
Figure 7 shows segmented memory successfully capturing 1,000
events in 3.27274 seconds. Traditional memory architecture
would require 2.7 Gpts of memory to accomplish the same result.
This memory is not available on any scope in the market.
Figure 7. Segmented memory efficiently manages the memory to capture
up to 1,000 segments of interest to you, making it an effective ultra-deep
memory oscilloscope that can easily capture infrequent events and
anomalies.
Segmented memory + serial decode
Segmented memory works in conjunction with serial protocol
decode. For example, by setting the trigger condition to “CAN
serial bus error,” segmented memory captures and stores only
CAN error packets and stitches together each segment for easy
viewing. You can quickly compare time tags in the event lister to
discover time intervals between errors.

decode resulting in maximum insight into serial bus.
