I'm using AWR2243 and for computing ramp end time it requires to compute as well how long the ADC sampling time will last.
But I wonder how the sampling is being designed into the RF chips, does the first ADC samples being sampled at t = 0 or is it t = 1/fs ?
Depending on how RF chips do sampling it means sampling time shall be either computed as:
ADCSamplingTime = NSamples / fs
ADCSamplingTime = (NSamples-1) / fs
