Basic Digital Operation

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 only be played back by the dual ARB player. This is true for downloaded waveform files (downloading files is described in the E8257D/67D PSG Signal Generators 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 3- 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 86.

To properly set up the instrument:

1.Select the waveform.

2.Modify the signal generator settings as desired.

3.Turn on the dual ARB.
