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 5-1shows the PSG’s display.

(Some ARB formats have a second page)

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 the active modulation, you must modify the default settings before you save the header information with the waveform file (see “Modifying Header Information in a Modulation Format” on page 90).

NOTE	Each time an ARB modulation format is turned on, a new temporary waveform file
	(AUTOGEN_WAVEFORM) and file header are generated, overwriting the previous
	temporary file and file header. Because all ARB formats use the same file name, this happens
	even if the previous AUTOGEN_WAVEFORM file was created by a different
	ARB modulation format.
