Model 4200A-SCS Parameter Analyzer Reference Manual Section 13: LPT library function reference4200A-901-01 Rev. C / February 2017 13-9LPT commands for general operationsGeneral operation commands include commands to control timing, execution, communications, andtest status.clrscnThis command clears the measurement scan tables associated with a sweep.Usageint clrscn(void);DetailsWhen a single sweepX command is used in a test sequence, there is no need to program a clrscncommand because the execut command clears the table. The clrscn command is only requiredwhen multiple sweeps and multiple sweep measurements are used in a single test sequence.Exampledouble res1[14], res2[14];.conpin(SMU1, 1, 0);conpin(SMU2, 2, 0);conpin(GND, 3, 0);forcev(SMU1, 4.0); /* Apply 4 V to gate. */smeasi(SMU2, res1); /* Measure drain current in *//* each step; store results *//* in res1 array. */sweepv(SMU2, 0.0, 14.0, 13, 2.0E-2); /* Make *//* 14 measurements *//* over a range of 0 V to 14 V. */clrscn(); /* Clear smeasi. */forcev(SMU1, 5.0); /* Apply 5 V to gate. */smeasi(SMU2, res2); /* Measure drain current in *//* each step; store results in *//* res2 array. */sweepv(SMU2, 0.0, 14.0, 13, 2.0E-2); /* Perform *//*14 measurements *//* over a range 0 V through 14 V. */
