Both the Saved Header Settings column and the Current Inst. Settings column now display the same settings; the Saved Header Settings column lists the settings saved in the file header.

The file header contains the following signal generator settings:

32- Character

A description entered for the header, such as a the waveform’s function (saved/edited with the Edit

Description:

Description key, see Figure 3- 2 on page 75).

Sample Rate:

The ARB sample clock rate.

Runtime Scaling:

The Runtime scaling value. Runtime scaling is applied in real- time while the waveform is playing.

 

This setting can be changed only for files in the dual ARB player.
