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.
