A.8

*OPC? — OPERATION COMPLETE QUERY

*OPC?

Syntax:

*OPC?
Return value: <1> (ASCII) placed in output queue when power supply has completed operation.

Description: Indicates when pending operations have been completed.When all pending operations are com-

plete (all previous commands have been executed and changes in output level have been completed)
a “1” is placed in the Output Queue. Subsequent commands are inhibited until the pending operations
are completed. *OPC? is intended to be used at the end of a command line so that the application pro-
gram can monitor the bus for data until it receives the “1” from the power supply Output Queue. (See
example, Figure A-1.)

A.9

*OPT? — OPTIONS QUERY

*OPT?

Syntax:

*OPT?
Returns string determined by power supply model.

Description: Causes the power supply to return an ASCII string which defines the functionality of the power supply.

The functionality is defined as follows:

A.10 *RCL — RECALL COMMAND

*RCL

Syntax:

*RCL <integer> (1 to 40)

Description: Restores power supply to previously defined levels of output voltage, output current, overvolt-

age protection, and overcurrent protection.This command selects one of the 40 power supply
memory locations, each of which stores values for output current, output voltage, overvoltage protec-
tion, and overcurrent protection. The following parameters are affected by *RCL: CURR[:LEV][:IMM]
VOLT[:LEV][:IMM] CURR:PROT[:LEV] VOLT:PROT[:LEV]. The recall function also sets the unit
to operating parameters to SCPI compatible mode, or device clear operation and output on or off. If
the recall value was not initialized by the *SAV command, but from an edit save or front panel save,
the output condition will remain unchanged along with the language preferences. (See example, Fig-
ure A-1.)

STRING DATA

MEANING

CAL

Support for CALibrate is present.

RL3

Hardware switch controlling remote/local is functional. Unit can be used to take measurements in local
mode, but all other functions require the unit to be in remote mode (REN must be asserted).

M40

Indicates the number of memory steps supported.

D16

Indicates the number of characters supported for user messages on LCD.
