B-3
B.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:
FIGURE B-1. GPIB COMMANDS
B.10 *RST — RESET COMMAND
*RST
Syntax: *RST
Description: Resets power supply to the power on default state. The power supply is programmed to the power
on values of the following parameters: CURR[:LEV][:IMM] = 0, VOLT[:LEV][:IMM] = 0, OUTP[:STAT]
= OFF. If the power supply is in either an overvoltage or overcurrent state, this condition is reset by
*RST. (See example, Figure B-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 requeire the unit to be in remote mode (REN must be asserted).
*CLS Power supply clears status data.
*ESE 60 Power supply enables bits 5, 4, 3 and 2, allowing command error, execution
error, device dependent error and query error to set the Event Status
Summary bit when an STB command is executed.
*ESE? Returns 60, (value of the mask) verifying that bits 5, 4, 3 and 2 are enabled.
*ES Unknown command will set command error (Bit 5).
*ESR? Returns 32 (bit 5 set), indicating Command Error has occurred since the last
time the register was read.
*IDN? Controller returns character string: "KEPCO,MST,1,V3.0-3.0"
*OPC Allows status bit 0 to be set when pending operations complete
VOLT 21;CURR 3 Sets output voltage to 21V, output current to 3A
*ESR Returns 129 (128 + 1, power on, bit 7 = 1, operation complete, bit 1 = 1)
*ESR Returns 0 (event status register cleared by prior *ESR?)
VOLT 15;CURR 5;*OPC? Sets output voltage to 15V, output current to 5A, puts “1” on output bus when
command operations are complete.
*RST Power supply reset to power on default state.
*SRE 40 When ESB or QUES bits are set (Table B-3), the Request for Service bit will
be set.
*SRE? Returns the value of the mask (40).
*STB? For example, the Power supply responds with 96 (64 + 32) if MSS and the
Event Status Byte (Table B-3) summary bit have been set. The power supply
returns 00 if no bits have been set.
VOLT 25 Power supply voltage commanded to 25V.
VOLT:TRIG 12 Programs power supply voltage to 12V when *TRG received.
INIT Trigger event is initialized.
*TRG Power supply reverts to commanded output voltage of 12V.
*TST? Power supply executes self test and responds with 0 if test completed
successfully, with 1 if test failed.
