MBTSVC 111609
*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 *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 A-1.)
A.11 *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.)
A.12 *SRE? — SERVICE REQUEST ENABLE QUERY
*SRE?
Syntax: *SRE? Response: = value from 0 - 255 per Table A-3.
Description: Reads the Service Enable Register. Used to determine which events of the Status Byte Register are
programmed to cause the power supply to generate a service request (1 = set = function enabled, 0 =
reset = function disabled). Related Commands: *SRE, *STB? (See example, Figure A-1.)
