Dual Arbitrary Waveform Generator

Arbitrary (ARB) Waveform File Headers

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). In this procedure, we work within the Custom digital modulation format. All ARB modulation formats and the dual ARB player access the file header using the same key presses, except that for 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 5-1 on page 89), open the Header Utilities menu: Press ARB Setup > Header Utilities

The default header for the Custom digital modulation waveform is displayed (see Figure 5-2). In the Saved Header Settings column, the signal generator settings for the active format are shown as Unspecified, which means that no settings have been saved to the file header. If a setting is unspecified in the file header, the current value for that setting does not change when the waveform is selected for later use.

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 two).
