Arbitrary (ARB) Waveform File Headers
An ARB waveform file header enables you to save instrument setup information (key format settings) along
with a waveform. When you retrieve a stored waveform, the header information is applied so that when the
waveform starts playing, the dual ARB player is set up the same way each time.
Headers can also store a user-specified 32-character description of the waveform or sequence file.
A default header is automatically created whenever a waveform is generated, a waveform sequence is
created, or a waveform file is downloaded to the PSG (for details on downloading files, see the PSG
Programming Guide).
The following signal generator settings are saved in a file header:
• ARB sample clock rate
• Runtime scaling (only in the dual ARB player)
• Marker polarity (markers 1 through 4)
• Marker routing functions (markers 1 through 4)
— ALC hold
— Alternate amplitude
— RF blanking
• High crest mode (only in the dual ARB player)
• Modulator attenuation
• Modulator filter
• I/Q output filter (used when routing signals to the rear panel I/Q outputs)
• Other instrument optimization settings (for files generated by the PSG) that cannot be set by the user.
