Saving and Recalling Waveforms
The TLS 216 Logic Scope can save and recall waveform groups into any of the
four internal reference memories of the logic scope. (The logic scope retains the
stored reference groups even if powered off or unplugged.) It can also save
groups to and recall them from a 720 KByte or 1.44 MByte floppy disk inserted
in the logic scope floppy drive. This article describes both storage in internal
memory and to floppy disk.
To Understand Reference Waveform Groups
To make best use of the save and recall waveform feature, first consider why you
might use it. Then read about how the logic scope stores, recalls, and displays
waveforms — using either internal or external (floppy disk) storage.
Use Save/Recall waveform to save live waveform groups as reference waveform
groups, so you can do following tasks.
H
Clear live waveforms from the screen, creating display space for additional
waveforms without loosing the data from those waveforms.
H
Save waveform data while the logic scope is powered off.
H
Collect waveform data in a media (floppy disk) that, once stored, you can
archive, transport, and otherwise use independent of the logic scope.
Each reference group you save to contains saved waveforms (when not empty)
instead of live waveforms. This reference group of waveforms resembles a live
waveform group except the waveforms are static (saved; not being newly
acquired). Understanding how to define live waveform groups makes how to
save those groups as reference groups easier to understand. See Grouping
Waveforms on page 3–55 to learn about groups.
Internal storage operates as follows.
H
The logic scope can store up to four reference groups of waveforms.
H
The logic scope can store up to 16 waveforms internally. These waveforms
can be allocated among the four reference groups in any combination. For
example, the logic scope can store one group of 16 waveforms, or two
groups with 5 and 11 waveforms each, and so on.
H
The logic scope displays reference groups from reference memory using the
MORE menu.
