Command system EN Argument Instructions ⚫ FUNCtion:PULSe:DPeriod and FUNCtion:PULSe:WIDTh commands affect the same arguments. ⚫ The pulse duty cycle is defined as: Duty cycle = 100 x pulse width ч period Pulse width is the time from the 50% threshold on the rising edge to the 50% threshold on the next falling edge. ⚫ The pulse duty period ranges from 0% to 100%. The pulse duty cycle is limited by the minimum pulse width and edge time, though, which prevents setting a duty period to 0% or 100%. For example, for a 1 kHz pulse waveform, the pulse duty cycle is usually limited to a range of 0.002% to 99.998%, limited by a minimum pulse width of 16ns. ⚫ Pulse width limits:
The specified pulse duty period must meet the following limits determined by the minimum pulse width (Wmin). The instrument will adjust the duty cycle as needed to meet the specified period. Pulse duty period ≥ 100 Ч (minimum pulse width/pulse cycle) Pulse duty period ≥ 100 Ч (1-2 Ч minimum pulse width/pulse cycle) Return format Return the current duty cycle as a scientific count. Example SOURce1:FUNCtion:PULSe:DPeriod 30 /* Set channel 1 duty cycle to 30%*/ 3.13.8 SOURce :FUNCtion:PULSe:WIDTh Command format SOURce :FUNCtion:PULSe:WIDTh |MINimum|MAXimum SOURce :FUNCtion:PULSe:WIDTh? [MINimum|MAXimum] Function description Set the pulse width of the pulse.
