Language Dictionary 3Keysight Models 6811C, 6812C, and 6813C Programming Guide 57Calibration Subsystem CommandsThe commands in this subsystem allow you to do the following:– Enable and disable the calibration mode– Change the calibration password– Calibrate the current and voltage output levels, and store new calibrationconstants in non-volatile memory.Subsystem syntaxCALibrate | CALibration:COUNt? Returns the calibration count of the ac source:CURRent:AC Begin AC current programming calibration sequence:EXTernal Initiates calibration of the external current measurement:MEASure Begin current measurement calibration sequence:DATA Input a calibration measurement:DATA? Returns the present value of the phase calibration:DATE Input a calibration date:IMPedance Begin output impedance calibration sequence:LEVel Advance to next calibration step (P1 | P2 | P3 | P4):PASSword Set calibration password:PHASe:AUXiliary Initiates calibration of the auxiliary output phase:PWM:FREQuency Trim pulse width modulator frequency:RAMP Trim pulse width modulator ramp:SAVE Save new cal constants in non-volatile memory:SECure:CODE Set calibration password:STATe [, ] Unsecures or secures the instrument for calibration:SHUNt Allows you to enter the external current shunt value:STATE [, ] Enable or disable calibration mode:STRing Stores a message in calibration memory
