I have a 3 questions about the MCC172 card.
1. In the datasheet of our MCC172 acquisition cards, there is an offset error value of ± 5.1mV. Does this value limit our accuracy to ±5.1mV or do we consider that the data can only be offset by a maximum of 5.1 mV and that in the post-analysis we can simply recenter to 0 mV.
2. Why is the dynamic range 100 dB? We have a 24-bit ADC and I find 144 dB as dynamic range.
3. Does the dynamic range means that the voltage input can varie between 33uV (noise flood) and 3.3 V (100 dB = 10^5, 10^5 * 33uv = 3.3 V ) if we want correct measurement?
Thank you,
