# sampling rate and bit resolution for Scanning Probe Microscopy

2 Forced line breaks using 2 x spaces at the end of each line in the list, to make each item display on a separate line, and not in one long "run on" paragraph.

I am trying to compare two products and see which one offers higher performance in terms of sampling rate and bit resolution.

Below are the specs I was able to gather from product1 and product 2. (I am not sure if I am looking at the relevant specs though.)

product 1Product 1:
Input: ADC @ 400 kS/s, 18 bit
2 HF ADC inputs @ 50 MS/s, 16 bit
Output: DAC outputs @ 200 kS/s, 16 bit

product2Product 2:
Input: 20-bit @ 60 kS/s, 22-bit @ 1 kS/s (oversampling)
Output: 20-bit, 1-ppm precision, 1 MS/s

I think it's true that higher resolution in bits is going to result in better performance. However, it seems product 1 has a higher sampling rate.

Could someone tell me which product will result in finer resolution in both input and output and why?
