The upper left plot shows the linear relation between the mean error in the frequency measurement and the reference frequency.

*max(abs(fcor-fref))*is the maximum absolute difference of the measured, clock corrected frequency from the reference frequency for the 100-300 points samples at each reference frequency. This maximum error seen in the test stayed below the 1:106line except for some points at frequencies over 200 KHz. The maximum error also generally stayed below the frequency discretization level, suggesting that after the clock is corrected, almost all of the remaining error is due to the discretization.
