We currently use a ADC212 and are looking to upgrade to a ADC 212-100.
The ADC is used to measure either a pair or a single 100Hz AC sinwave for magnetic B-H loop measurments after amplification. Input signal range is in the order of +/- 200 mV. We require a minimum of 12 bit vertical resultion, so 8 bit faster systems are not feasible
My first question is what is the highest resolution of time base that can be measured on a single cycle of a 100Hz wave (10mS) firstly with single channel then double channel measurements?
Next, through triggering is it possible to examine a smaller proportion of the wave for example 1/10 of it so a 1mS window of measurement? It seems on the ADC212 it can be diffucult to advance the trigger far into the 100Hz wave at smaller time scales. I assume this is due to the size of the buffer memory on the ADC. What would be the farthest you could advance into the wave at different small time intervals? For example 100uS interval
Again what would be the highest time resolution that can be measured for both a single and dual channel measurement?
Thank you in advance.
