Creating a File Header for a Modulation Format Waveform
When you turn on a modulation format, the PSG generates a temporary waveform file
(AUTOGEN_WAVEFORM), with a default file header. The default header has no signal generator
settings saved to it.
This procedure, which is the same for all ARB formats, demonstrates how to create a file header for
a Custom digital modulation format.
1. Preset the signal generator.
2. Turn on the Custom modulation format:
Press
Mode > Custom > ARB Waveform Generator > Digital Modulation Off On to On
A default file header is created, and the temporary waveform file (AUTOGEN_WAVEFORM) plays.
Figure 3- 1 shows the PSG’s display.

At this point, a default file header has been created, with default (unspecified) settings that do
not reflect the current signal generator settings for the active modulation. To save the settings for
