Digital　store　oscilloscope　is　a　type　of　oscilloscope　that　changes　analog　signal　tested　into　digital　signal　and　stores　it　and　displays　it　in　analog　or　digital　signal　way.　Both　analog　oscilloscope　and　digital　store　oscilloscope　are　frequently　used　for　observing　signal　waveform　and　researching　pulse　signal　parameters.　Insuring　the　accurateness　of　measurements,　it＇s　necessary　to　calibrate　all　kinds　of　specifications　of　oscilloscopes.　Whereas　there　isn＇t　any　oscilloscope　automatic　calibration　system　in　our　country,　a　digital　store　oscilloscope　automatic　calibration　system　is　designed　and　realized　using　Microsoft　Visual　C++　6.0　programming　environment　based　on　GPIB　interface　in　this　paper.　It　can　calibrate　digital　store　oscilloscope　quickly　and　automatically,　store　the　calibration　data　in　database　and　then　make　a　calibration　certificate　automatically　by　VBA.　The　system　can　support　new　digital　store　oscilloscopes　easily　by　writing　new　oscilloscope　controlling　files.
