Viewing and Modifying Header Information

The following example uses the factory–supplied waveform file RAMP_TEST_WFM.
1. From BBG media, select the waveform RAMP_TEST_WFM:
a. Press Mode > Dual ARB > Select Waveform.
b. In the Segment On column, highlight the waveform RAMP_TEST_WFM.
c. Press Select Waveform.
2. Open the Header Utilities menu:
Press More > Header Utilities
The Figure 8- 5 shows the default file header for the factory–supplied waveform RAMP_TEST_WFM.
The Header Field column lists the file header parameters; use the Page Down key to see them all.
The Saved Header Settings column shows that most of the settings are Unspecified.
Unspecified means that there is no setting saved for that particular parameter.
