Calibration Commands
The following calibration commands are required to calibrate the Electronic Load. They are used in the program examples included in this section. Refer to the Agilent Electronic Loads Programming Reference Guide for HPSL commands.
CALibration:[MODE] ONOFF
Turns the calibration mode on or off.
CALibration:LEVel:HIGH <NRf>
Enters the actual high level value (measured by an external instrument) that corresponds to the present high level setting. An error is generated if the high level value is not greater than the low level value. Both high and low CAL: LEV commands must be sent before the constants are recalculated and stored in RAM.
CALibration:LEVel:LOW <NRf>
Enters the actual low level value (measured by an external instrument) that corresponds to the present low level setting. An error is generated if the low level value is not less than the high level value. Both high and low CAL: LEV commands must be sent before the constants are recalculated and stored in RAM.
CALibration:TLEVel[:HIGH] < NRf >
Enters the actual transient level value (measured by an external instrument) that corresponds to the present transient setting. The low level value of the main DAC is used as the low point for the transient calibration. Note that for the middle and high resistance ranges, the transient level is LOWER than the high level of the main DAC.
CALibration:MEASure:HIGH <NRf>
Enters the actual high level value (measured by an external instrument) that corresponds to the present high level setting. The input signal must remain applied to the Electronic Load while this command is executed because the unit takes a reading with the readback DAC to calibrate itself. An error is generated if the high level value is not greater than the low level value. Both high and low CAL:MEAS commands must be sent before the constants are recalculated and stored in RAM.
CALibration:MEASure:LOW <NRf>
Enters the actual low level value (measured by an external instrument) that corresponds to the present low level setting. The input signal must remain applied to the Electronic Load while this command is executed because the unit takes a reading with the readback DAC to calibrate itself. An error is generated if the low level value is not less than the high level value. Both high and low CAL:MEAS commands must be sent before the constants are recalculated and stored in RAM.
