Explanation
This command selects the output waveform of the instrument when Mod, Sweep and Burst are disabled.
This command selects the carrier waveform corresponding to the function when Mod, Sweep or Burst is currently enabled.
When the :FUNCtion DC command is received, the instrument will disable Mod, Sweep or Burst if it is currently enabled.
Return Format
The query returns SIN, SQU, RAMP, PULSE, NOISE, HARMONIC or CUSTOM.
When waveform other than SINusoid|SQUare|RAMP|PULSe|NOISe|USER|HARMonic|CUSTom| is selected, the return value is
the corresponding parameter in the table above.
Note: when USER (arbitrary waveform) is currently selected, the query returns the return value corresponding to the built-
in waveform currently selected in the arbitrary waveform.
Example
The command below selects square waveform.
:FUNCtion SQUare
