Frequency Definition for Arbitrary Waveform (33120A)

Hi there, I am writing a program to upload an arbitrary waveform to the 33120A function generator. My goal is to create a square wave where I can set the duty cycle lower than the 20% limit on built-in square wave.

 

It looks like I can send anywhere from 8 to 16,000 points and then set the frequency. But I am not sure if the frequency applies to the time between points or to the waveform as a whole. For example, I make a waveform that is 1,000 points long, and I have 100 points at 1 and 900 points at 0, and want the whole waveform to repeat every 10 ms. Do I set the frequency to 100 Hz and the instrument will calculate the time between points required?
