[: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
