HP E1418A manual CALibration CALibrationSTORe, CALibrationTEST?

CALibration

CALibration:STORe

CALibration:STORe loads the stored non-volatile memory calibration constants with the calibration constants currently in use by the module.

Parameters None.

Comments ∙ This command sets the calibration constants in non-volatile memory if the CAL Store Enable Jumper is properly set (see page 156). Non-volatile memory has finite life, based upon the number of writes. Use this command sparingly.

∙At power-on, calibration constants stored in non-volatile memory are loaded into the module where they are used during output operations.

∙When this command is received, the checksum is verified using the constants currently in use by the module. If the checksum does not verify, the non-volatile memory is not updated and an error is generated.

∙Refer to Appendix D, “ Voltage/Current Output Adjustment” , starting on page 154, for additional information about this command.

CALibration:TEST?

CALibration:TEST? performs an internal rough check of the calibration of each channel and returns an integer indicating the channel calibration condition. Calibration is checked to approximately ± 2%.

Parameters Returns: unsigned 16-bit integer (uint16).

Comments ∙ Following the completion of this query all outputs are disabled and set to 0 Volts or 0 Amps based on the channel mode.

∙This query returns a 16-bit integer indicating the calibration status of each channel.

–Bits set to 0 indicate no calibration errors were found.

–Bits set to 1 indicate a channel with questionable calibration.

–Bits 0–15 corre spond to channels 1–16, respectively.

∙If the trigger system is waiting for a trigger when this command is received, an error is generated.
