I'm using the PIT to hardware trigger the ADC module. I was able to successfully capture a 1 kHz test signal at a 100 kSPS rate. I then implemented hardware averaging. I expected the sample rate to drop to the base sample rate divided by the number of averages (i.e. 100 kSPS / 4 avg. = 25 kSPS). Instead it dropped by a factor of 3 (33.33 kSPS). I found the other settings resulted in sample rates that were (3/4 * number of avg's). So an average of 8 resulted in a sample rate reduction of 6. Has anyone else confirmed this? Is the intended behavior?
No Averaging - 100 kSPS Assumed Sample Rate, 1 kHz Test Signal
Averaging of 4 - 25 kSPS Assumed Sample Rate, 1 kHz Test Signal
Averaging of 4 - 33.33 kSPS Assumed Sample Rate, 1 kHz Test Signal
