
Duty cycle deviation is limited by the minimal duty cycle of pulse wave and current edge time.
Comprehensive Example
Make the instrument work in pulse modulation (PWM) mode, then set a sine wave with 1kHz from the internal of
the instrument as a modulation signal and a pulse wave with 10kHz frequency, 2Vpp amplitude and 50% duty cycle
as a carrier wave signal, finally, set duty cycle deviation to 40%. Specific steps are seen as following:
1) Enable Pulse Width Modulation (PWM) Function
Press Menu → Modulation → Type → Pulse Width Modulation in turn to start the PWM function.
2) Set Modulation Signal Parameter
Press Parameter softkey and the interface will show as following:
Press corresponding softkey, then enter required numerical value, and select the unit.
