This option activates the 2-channel arbitrary function generator built into the oscilloscope.
The signal output is via 2 BNC outputs on the front of the oscilloscope.
The option offers the following waveforms in the Keysight (formerly Agilent's electronic measurement technology) oscilloscope of the 6000X series:
Arbitrary, sine, square, pulse, triangle, ramp, noise, DC.
The software option enables the user to convert a signal recorded with the oscilloscope into a stimulus signal file at the touch of a button - and even to modify it within the scope of the oscilloscope.
In addition, any user-defined signals can be created using the Keysight software (formerly Agilent's electronic measurement technology) BenchLink Waveform Builder Pro.
