Duty cycle during sweeping

Hello,
I am new to this forum. I have a question about programming for PCGU 1000. I use Labview to generate a function with the following parameters:
Voltage: 5.5
sweep freq.: 61000 to 62000 Hz
time: 3 secs

I would like to know if it is possible to set the duty cycle during sweeping option? Kindly advice.
Cheers
