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).
