PULSe:DCYCle {<
percent
>|MINimum|MAXimum}
Set the duty cycle in percent for square waves only . Duty cycle
represents 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 square
wave to another function. When you return to the square wave
function, the previous duty cycle is used. The
APPLy
command
automatically sets the duty cycle to 50% for square waves.
œ
Possible Conflict with Output Frequency : The duty cycle is auto-
matically adjusted if you select a frequency that is not valid with the
present duty cycle. For example, if you set the duty cycle to 70% and
then change the frequency to 8 MHz, the function generator will
automatically adjust the duty cycle to 60% (the upper limit for this
frequency).
From the remote interface, a -221, “Settings conflict” error
is generated and the duty cycle is adjusted.
PULSe:DCYCle? [MINimum|MAXimum]
Query the duty cycle setting. Returns a value in percent.
