Chapter 4 Remote Interface ReferenceOutput Configuration CommandsPULSe:DCYCle {|MINimum|MAXimum}Set the duty cycle in percent for square waves only. Duty cyclerepresents the amount of time per cycle that the square wave is high.The default is 50%. [ Stored in volatile memory ]œ Duty cycle: 20% to 80%, in 1% increments (frequency ˆ 5 MHz).40% to 60%, in 1% increments (frequency > 5 MHz).The default is 50%.œ The duty cycle setting is remembered when you change from squarewave to another function. When you return to the square wavefunction, the previous duty cycle is used. The APPLy commandautomatically sets the duty cycle to 50% for square waves.œ Possible Conflict with Output Frequency: The duty cycle is automaticallyadjusted if you select a frequency that is not valid with thepresent duty cycle. For example, if you set the duty cycle to 70% andthen change the frequency to 8 MHz, the function generator willautomatically adjust the duty cycle to 60% (the upper limit for thisfrequency). From the remote interface, a -221, “Settings conflict” erroris generated and the duty cycle is adjusted.4PULSe:DCYCle? [MINimum|MAXimum]Query the duty cycle setting. Returns a value in percent.147
