Abstract: In the tech nology of automatisc test and the system ment of synth etical measure and control, solving the comm unication

problem betw een controller equipment and in strument becomes one of important problems The SCPI rules all th e communication command

's content and format, w hich brings forw ard the higher r equest to soft developm ent of pr ogrammable in strument T he paper introduces tw o

kinds of SCPI command and their m ost synta rules, advances a realization meth od of stan dardization and m odularization's SCPI command

interpreter based on the tree module Th e paper research es the S CPI's parse and application m ethod in program mable instrument 's embedded

Linu operation system environment, and proves that the comm and interpreter has th e advantages of quick parse speed, full par se com

m and, good transplant characteristic and so on , so it plays a active support role to develop th e modern pr ogrammable instrument
