Figure 9-3 Waveform Sequence Softkeys
A waveform sequence is a file that contains pointers to one or more waveform segments or other
waveform sequences, or both. This lets the signal generator play multiple waveform segments, or
other sequences, or both thereby eliminating the need to stop waveform playback just to select
another waveform.
The segments that a waveform sequence points to are
not automatically stored when you store the
sequence; you must also store the individual segments or they are lost when you turn off or reboot
the signal generator. If the segments are located in internal/external media, you must load them
into BBG media prior to selecting a waveform sequence (see page 189 ). If you attempt to play a
sequence without the segments loaded into BBG media, the signal generator reports:
ERROR:
629, File format invalid
. If this happens and the segments are not stored in internal/external
media, you must recreate the segments using the same file names that the sequence points to
before you can play the sequence.
Creating a Sequence
A waveform sequence can contain up to 1,024 segments and have both segments and other
sequences (nested sequences). The signal generator lets you set the number of times the segments
and nested sequences repeat during play back. But there is a difference between repeating a
