SOURce

Subsystem

This subsystem is used to control output functions, shape and

parameters, frequency, amplitude and amplitude modulation, and filter

type. Optional nodes were omitted from these commands. Factory

defaults after *RST are shown in bold typeface. Parameter low and

high limits are given where applicable.
