【Abstract】 An error test system using 8098 microcontroiler to replace the conventional dividing fre-quency and comparing phase instrument is presented. With the system, the aurrent error test for theworktable is realized, and the main error source of the worktable is found out by means of FFT spec-trum.更多还原
