1% to 99% (frequency < 100KHz) 
20% to 80% (100KHz < frequency < 5 MHz) 
40% to 60% (5 MHz < frequency < 10 MHz) 
50% (frequency > 10 MHz 
If the frequency is changed and the set duty cycle 
cannot support the new frequency, the highest 
duty cycle available at that frequency will be used. 
A ―-221‖ error will be generated from the remote 
terminal. 
For square waveforms, the Apply command and 
AM/FM modulation modes ignore the duty cycle 
settings.  
Syntax 
SOURce[1]:SQUare:DCYCle {< percent> 
|MINimum|MAXimum} 
Example 
SOUR1:SQU:DCYC MAX 
Sets the duty cycle to the highest possible for the 
current frequency. 
Query Syntax 
SOURce[1]:SQUare:DCYCle? {MINimum|MAXimum} 
Return Parameter 
<NR3> 
Returns the duty cycle as a percentage. 
Query Example 
SOUR1:SQU:DCYC?
