Special Features:

Internal and external modulation enabled to allow combined amplitude and frequency or phase modulation; pulse modulation with other external pulse source; allows for am, fm, pulse, and/or phase modulation; internal modulation source for waveforms: sinusoidal, square, and triangular

Properties:

An instrument which produces a continuous audio and/or radio frequency voltage, and which is designed for test purposes only. It may provide an output at one or more fixed frequencies or be continuously variable over one or more bands. The fixed frequency type is distinguished from calibrator, frequency in that it is a voltage source and is not primarily intended for checking frequencies from other sources. Excludes generator, interference.
