How to speed up the calibration process at frequency 0.02 hz?

[Anonymous]

Dear all,

   

I managed to obtained a very low frequency as 0.02 hz by using frequency divider (  divide by 1000). However, the calibration process become very slow. It took almost 3 minutes to finish the calibration. can someone explained why ? and how to make the time for the calibration to be less than 15 second at the same frequency 0.02 hz?

   

TQ

To be honest: I do not have the lightest clue what kind of calibration you are talking about.

   

Measuring a 0.02 Hz frequency will always take 1/0.02 seconds which is about 50 seconds. When you average 4 of those measures (calibration??) you get to your 3 minutes requirement.
