34461A Taking periodic samples

I would like to take periodic measurements spaced 20 ms apart using the 34461A. I am using previous code I wrote for a 34410A but found the 34461A does not have a sampling:source option so you can only set the trigger delay to determine the spacing between samples. On the 34410A I just set the sampling interval to longer than the sampling time so I was able to get a deterministic spacing between samples.

With only the trigger delay the time between samples becomes (Trig_Delay+Sample_time), but sample time isn't constant, so you have to approximate(?) the timing between samples. Is there something here I am missing or is this a loss of functionality between the older 34410A and the newer 34461A?
