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 157). 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 155,

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 correspond to channels 1–16, respectively.

• If the trigger system is waiting for a trigger when this command is received, an

error is generated.
