Dual Arbitrary Waveform Generator
Arbitrary (ARB) Waveform File Headers
Playing a Waveform File that Contains a Header
After a waveform file (AUTOGEN_WAVEFORM) is generated in a modulation format and the format is
turned off, the file becomes accessible to and can be played back in only the dual ARB player. This is also
true for downloaded waveform files (downloading files is described in the Programming Guide). When the
waveform is selected for playback, the saved header information is used by the signal generator. Some of
these settings appear as part of the labels of the softkeys used to set the parameters, and also appear on the
dual ARB summary display (see
Figure 5-8 ).
NOTE
The signal generator used to play back a stored waveform file must have the same options
as are required to generate the file.
For details on applying file header settings and playing back a waveform, see “Playing a Waveform” on
page 102 .
To properly set up the instrument:
1. Select the waveform.
2. Modify the signal generator settings as desired.
3. Turn on the dual ARB.
