This appendix provides information for making accurate time
interval measurements with the timing analyzer.
Accurate time interval measurements depend primarily on the time
interval resolution of the timing analyzer. If you have a good time
interval resolution, using statistics can improve the accuracy of a
measured time interval by the amount described in the equations
which you will find in this appendix. Accurate statistical
measurements can be made only if the input intervals are a uniform
distribution of the interval to be measured. The following
information describes important aspects in making accurate time
interval measurements.
Resolution is a measurement of the precision of a timing trace and
depends on the following factors:
Sample Period.
Interchannel Skew.
Memory Depth.
