Dual Arbitrary Waveform Generator

Arbitrary (ARB) Waveform File Headers

Storing Header Information for a Dual ARB Player Waveform Sequence

When you create a waveform sequence (described on page 101), the PSG automatically creates a default file header, which takes priority over the headers for the waveform segments that compose the waveform sequence. During a waveform sequence playback, the waveform segment headers are ignored (except to verify that all required options are installed). When you store the waveform sequence, its file header is stored with it.

Modifying and Viewing Header Information in the Dual ARB Player

Once a modulation format is turned off, the waveform file is available only to the dual ARB player. This is also true for downloaded waveform files. Because of this, future edits to a waveform’s header information must be performed using the dual ARB player.

To modify header information in the dual ARB player, the waveform file must be playing in the dual ARB player (although you can view the header information in the dual ARB player without playing the file)

You can reapply saved header settings by reselecting the waveform file for playback. When you do this, the values from the Saved Header Settings column are applied to the PSG.

Modifying Header Information

All of the same header characteristics shown in “Modifying Header Information in a Modulation Format” on page 90 are valid in the dual ARB player. This task guides you through selecting a waveform file and accessing the header for the selected file, then refers you back to the aforementioned procedure to perform the modifications.

1.Select a waveform:

a.Press Mode > Dual ARB > Select Waveform.

b.Using the arrow keys, highlight the desired waveform file.

c.Press the Select Waveform softkey.

2.Play the waveform: Press ARB Off On to On.

3.Access the header: Press ARB Setup > Header Utilities.

4.Refer to “Modifying Header Information in a Modulation Format” to edit the header information:

•For a default header, read the information in step one on page 90, then perform the remaining steps in the procedure.

•To modify an existing file header, start with step three on page 92.

The rest of this section focuses on the additional file header operations found in the dual ARB player.
