Verification and Calibration Appendix B
Series N5700 User’s Guide 113
Calibration
Refer to the “Equipment Required” section in this appendix for a list
of the equipment required for calibration. A general outline of the
procedure is as follows:
 Enter the calibration mode by providing the correct password.
The password is set at the factory to the model number. Once
calibration has been entered, the password can be changed by the
user. lf the password is incorrect, an error occurs.
 You do not have to do a complete calibration. If appropriate, you
may calibrate only the voltage or current functions and then save
the calibration constants.
 As each calibration sequence is completed, the instrument saves
the calibration constants and begins using them.
 Exit the calibration mode. Note that a Reset command also sets
the calibration state to OFF.
Calibration Procedure
Unless instructed otherwise, connect the +sense terminal to the
+output, and the -sense terminal to the -output.
When calibrating the unit using SCPI commands, most calibration
steps involve sending an *OPC? query to synchronize with the power
supply’s command completion before proceeding. The response from
the instrument must be read each time *OPC? is given.
NOTE
The CAL:LEV and CAL:DATA commands may take several seconds to complete.
If a timeout occurs in your VISA application, you may need to change the
VI_ATTR_TMO_VALUE in the ViSetAttribute function.

Voltage Programming and Measurement Calibration
Step 1. Connect the Agilent 3458A voltage input to an output.
Step 2. Select the full-scale voltage programming range. The value to program
a range must be the maximum voltage of the range.
CAL:VOLT <voltage>
Step 3. Select the first voltage calibration point.
