Next, we will explore how you can utilize Segmented Memory to capture
large amounts of waveforms with high fidelity. It works by capturing and
saving the data you want, and skipping everything between. What you get
is high resolution waveforms in high quantity (up to 1000). Note that you
can also use search and navigate features, as well as the lister, for
segmented acquisitions.
19 At this point, you should still be zoomed into a word with a label of
076. Press the [Acquire] front panel key, and go into the Segmented
menu.
20 Tap # of Segs, and when the keypad appears, tap Max. This will set it to
a value of 1000.
21 Press [Run/Stop] to restart acquisitions.
22 Tap the Segmented softkey to begin acquisition and analysis of 1000
words. This can take around a minute due to the large amount of
analysis; the result being nearly 2 seconds of acquisition.
23 When complete, tap Current Seg, open the keypad, and tap Max. Note the
timestamp of the final segment; it should be roughly 1.8 s.
