su bsystem of th e L4532A/34A Com m a n d Refer en ce. A gen er al sequen ce
for u sin g t hese comman ds for a fu ll adju stmen t is as follows:
CAL:SECURE:STATE OFF,<secure_code> // unsecure for calibration
CAL:STATE ON
CAL:RANGE 0.25 // first range
CAL:RANGE:SOURCE UPP // sets high voltage output
// read the output voltage_hi
CAL:RANGE:SOURCE LOW // sets the low voltage output
// read the low voltage_lo
CAL:RANGE:CHAN? (@1:4), <voltage_hi>,<voltage_lo> // sets all channels
CAL:RANGE 0.5 // do the next range
CAL:RANGE:SOURCE UPP // sets high voltage output
// read the output voltage_hi
CAL:RANGE:SOURCE LOW // sets the low voltage output
// read the low voltage_lo
CAL:RANGE:CHAN? (@1:4), <voltage_hi>,<voltage_lo> // sets all channels
// repeat for ranges 1, 2, 4, 8, 16, 32, 64, 128, 256
// on the 32, 64, 128 and 256 ranges, the high and low input is 0
CAL:STORe // put the new calibration constants into memory
CAL:STATE OFF
CAL:SECURE:STATE ON,<secure_code>
