FIGURE A-1. GPIB COMMANDS
A.13 *SRE — SERVICE REQUEST ENABLE COMMAND
*SRE
Syntax: *SRE where = value from 0 - 255 per Table A-3, except bit 6 cannot be pro-
grammed.
Description: Sets the condition of the Service Request Enable register. The Service Request Enable register
determines which events of the Status Byte Register are summed into the MSS (Master Status Sum-
mary) and RQS (Request for Service) bits. RQS is the service request bit that is cleared by a serial
poll, while MSS is not cleared when read. A “1” (1 = set = enable, 0 = reset = disable) in any Service
Request Enable register bit position enables the corresponding Status Byte bit to set the RQS and
MSS bits. All the enabled Service Request Enable register bits then are logically ORed to cause Bit 6
of the Status Byte Register (MSS/RQS) to be set. Related Commands: *SRE?, *STB?. (See exam-
ple, Figure A-1.)
*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? Power supply returns: KEPCO,ATE-100-10, 082495-001, 1.0.
*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
*SAV33 The present state of the power supply is stored in memory location 33.
*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.
*RCL33 Values in memory location 33 recalled (21V, 3A).
*RST Power supply reset to power on default state.
*SRE 40 When ESB or QUES bits are set (Table A-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 A-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.
