Internal source set-up
The internal source can modulate the carrier through up to three modulation paths (see Fig. 3-68).
You can configure these either:
• via the AM/FM/
Φ M sub-menus on the main screen, or
• directly from the Int sub-menu on the main screen.
In this section, we set up the internal source directly.

The soft tab shows the modulation path that Int is associated with — in this example, AM1. It
could also be FM1 or
Φ M1.
From this menu you can:
• Specify the source’s frequency and waveshape
