Basic Digital Operation

Arbitrary (ARB) Waveform File Headers

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 74).

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.

Modifying Header Information in a Modulation Format

This procedure builds on the previous procedure, explaining the different areas of a file header, and showing how to access, modify, and save changes to the information.

In a modulation format, you can access a file header only while the modulation format is active (on). This procedure uses the Custom digital modulation format. All ARB modulation formats and the dual ARB player access the file header the same way, except that in some modulation formats, you may have to go to page two of the first- level softkey menu.

1.From the first- level softkey menu (shown in Figure 3- 1 on page 73), open the Header Utilities menu:

Press ARB Setup > Header Utilities

Figure 3- 2 shows the default header for the Custom digital modulation waveform. The

Saved Header Settings column, shows that the signal generator settings for the active format are Unspecified, which means that no settings have been saved to the file header.

NOTE If a setting is unspecified in the file header, the signal generator’s current value for that setting does not change when you select and play the waveform in the future.

The Current Inst. Settings column shows the current signal generator settings for the active modulation. These settings become the saved header settings when they are saved to the file header (as demonstrated in Step 2).
