[:SOURce][:PULSe]:DCYCle[1|2]
Syntax [:SOUR][:PULS]:DCYC[1|2][?]
Form Set & Query
Description This command programs the duty cycle for a channel.
NOTE The duty cycle cannot be set:
• In direct mode. To query the clock source, see
“:TRIGger:SOURce” on page 87.
• If signal mode is set to NRZ. To query the signal mode, see
“:DIGital[1|2][:STIMulus]:SIGNal:FORMat” on page 31.
Parameter Numeric|MIN|MAX
Functional coupling Programming the pulse duty cycle also executes
[:SOURce][:PULSe]:HOLD DCYCLE so that the pulse duty cycle is held
constant when the signal frequency is changed.
Value coupling Width = (duty cycle / 100) * Period
Range coupling Frequency, Period
*RST value 50% (derived from WIDth and PERiod)
NOTE The DCYCle command holds the PERiod and WIDth values in
proportion (if one value is increased 50 %, the other value is also
increased 50 %). Its limits are therefore dependent on the limits of
PERiod and WIDth.
Example Set channel 1 duty cycle to 66%.
:DCYC1 66
