Return Format
The query returns a string. For example, SQU.
Example
:SOUR1:FUNC SQU /*Sets the waveform type of CH1 to Square.*/
:SOUR1:FUNC? /*Queries the waveform type of CH1 and the query returns SQU.*/
[:SOURce[<n>]]:FUNCtion:SQUare:DCYCle
Syntax
[:SOURce[<n>]]:FUNCtion:SQUare:DCYCle {<percent>|MINimum|MAXimum}
[:SOURce[<n>]]:FUNCtion:SQUare:DCYCle? [MINimum|MAXimum]
Description
Sets the Square duty cycle of the specified channel.
Queries the Square duty cycle of the specified channel.

Remarks
 Duty cycle is defined as the percentage that the high level of Square waveform takes up in the whole
period.
 When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default.
