Keysight E5260/E5270 Programming Guide, Edition 4 4- 41
Command Reference
Command Reference
CA
The CA command performs the self-calibration.
Modules that fail the self-calibration are disabled, and can only be enabled by the
RCV command.
After the CA command, enter the *OPC? command to confirm that the command
execution is completed.
Execution
Conditions
No channel may be in the HIGH VOLTAGE state (forcing more than ±42 V, or
voltage compliance set to more than ±42 V).
To perform the self-calibration correctly, the measurement terminals should be
opened.
Syntax
CA [ slotnum ]
Parameters
slotnum : Slot number that specifies the module to perform the self-calibration.
Integer expression. 1 to 8.
For HPSMU that uses two slots, set the greater slot number. For example, if it is
installed in slot 3 and 4,
slotnum must be 4.
If you do not specify slotnum , this command performs the self-calibration for the
mainframe and all modules.
If slotnum specifies the slot that installs no module, this command causes an error.
Example
Statements
OUTPUT @E5270;"CA"
OUTPUT @E5270;"*OPC?"
ENTER @E5270;A
NOTE
To send CA command to Keysight E5270B installed with ASU
If you send the CA command to the E5270B installed with the ASU (Atto Sense and
Switch Unit), the E5270B executes the self-calibration and the 1 pA range offset
measurement for the measurement channels connected to the ASUs. The offset data
is temporarily memorized until the E5270B is turned off, and is used for the
compensation of the data measured by the 1 pA range of the channels. The E5270B
performs the data compensation automatically and returns the compensated data.
Since the E5270B is turned on, if you do not send the CA command, the E5270B
performs the data compensation by using the pre-stored offset data.
