Waveform File Basics
There are two types of waveform files:
•A segment is a waveform file that you download to the signal generator.
For information on creating and downloading waveform files, refer to the Programming Guide.
•A sequence is a file you create in the signal generator that contains pointers to one or more
waveform files (segments, other sequences, or both).
For information on creating sequences, see page 137.
Signal Generator Memory
The signal generator has two types of memory:
• Volatile memory, baseband generator (BBG) media, where waveform files are played from or
edited.
• Non–volatile memory, either internal (int) or external (USB) media, where waveform files are
stored.
Dual ARB Player
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).
The dual ARB waveform player enables you to play, rename, delete, store, and load (external or
internal) waveform files in addition to building waveform sequences. The dual ARB waveform player
also provides markers (page 147), triggering (page 164), clipping (page 171), and scaling (page 180)
capabilities.
Most procedures in this section start from the Dual ARB menu, shown below.
