What are the function, features and characteristics of a signal generator?
Signal generator:
Many commercial units have these features:
Frequency: settable. Good frequency stability is an advantage.0.001Hz to 1 gHz., selectable as five or six digits.
Waveform can be selected. Sine, squarem triangle, positive ramp, negative ramp, pulse with variable duty ratio, arbitrary function, programmable.
Amplitude can be set
Output resistance can be set.
Rise time and fall time selectable.
Offset: Adjustable.
Builtin indicators when limits are exceeded.
