NOTE The MXG’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).
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 62 and familiarize yourself with that information.
See also: “Waveform Sequences” on page 137.
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.
NOTE Each time the instrument powers up, two factory–supplied segments are automatically
created in BBG media: RAMP_TEST_WFM and SINE_TEST_WFM.
There are additional sample waveforms that are available in the internal storage and that
can be loaded into memory. Refer to www.agilent.com and search on “Factory Default
N5182A” and “waveforms”.
