<h3>2: Baseband sample rate</h3>
This is the baseband sample rate in kS/s before interpolation (5) to produce the final stream that is sent to the HackRF device. Thus this is the device sample rate (8) divided by the interpolation factor (5).
Transmission latency depends essentially in the delay in the sample FIFO. The size of sample FIFO is calculated to give a fixed delay of 250 ms or 150000 samples whichever is bigger. Below is the delay in seconds vs baseband sample rate in kS/s from 48 to 800 kS/s. The 250 ms delay is reached at 600 kS/s:
