Storing, Loading, and Playing a Waveform Segment
Before using this information, you should be familiar with the signal generator’s file menus. If you
are not, refer to
“Working with Files” on page 56
and familiarize yourself with that information.
“Waveform Sequences” on page 192
.
The signal generator has two types of waveform media: non–volatile (internal or USB), and volatile
(BBG). BBG media is also called “working” media, because before you can play, edit, or include a
waveform file in a sequence, the waveform file must be loaded into BBG media.

Loading a Waveform Segment into BBG Media
Waveforms must reside in BBG media before they can be played, edited, or included in a sequence.
Cycling power or rebooting the signal generator deletes the files in BBG media.

he MXG/EXG’s ARB Waveform File Cache is limited to 128 files.
Consequently, once the 128 file cache limit has been reached, the
waveform switching speed will be much slower for additional files loaded
into the volatile waveform memory (BBG).
Each time the instrument powers up, two factory–supplied segments are
automatically created in BBG media:
RAMP_TEST_WFM
and
SINE_TEST_WFM
.
