ABSTRACT:
A time analyzer having an improved interpolator with temperature compensation. The time analyzer of the present invention can be operated in a wide range of temperatures without need of recalibration in the field. The device includes hardware for making a coarse time measurement. A fine time measurement is obtained by interpolating within a cycle of the master clock. A temperature correction look up table is produced which incorporates information unique to each analyzer. Information stored in the look up table of each instrument is used to correct time measurement for enhanced precision.
