Table B-2. CC Check Command String Agilent Model String Agilent 6030A ISET 17 VSET 2 Agilent 6031A ISET 120 VSET.2 Agilent 6032A ISET 50 VSET.6 Agilent 6033A ISET 30 VSET.2 Agilent 6035A ISET 5 VSET 5 Agilent 6038A ISET 10 VSET.6 Wait one second for power supply to settle. Send string: STS? and address the power supply to talk. The response should be: STS 2 indicating that power supply is in the CC mode. Send string: IOUT? and address the power supply to talk. The response should be: the ISET value set in step d. above. e. Turn off power supply, remove short from output, and read remainder of Section 3, except for LOCAL OPERATION, before connecting load to supply. Overvoltage Protection Setting For ease in setting the OVP trip voltage, use a looping program such as that listed in the check out procedure. This enables you to read the OVP trip voltage on the computer display while adjusting OVP at the power supply front panel. Blank Front Panel Option 001 81 Standard Commands for Programmable Instruments (SCPI) ABOUT THIS APPENDIX IF YOU WILL NOT BE PROGRAMMING USING SCPI COMMANDS, YOU DO NOT HAVE TO READ THIS APPENDIX. This appendix documents the Standard Commands for Programmable Instruments (SCPI), formerly known as TMSL, and applies to Agilent Models 603xA Series Autoranging System DC Power Supplies with the serial numbers shown on the cover page of this manual. READER PATH All readers should read the "INTRODUCTION" of this appendix. If you are unfamiliar with the Agilent 603xA power supplies, read through Section 3 of this Operating manual first, then return to this appendix. If you are unfamiliar with SCPI, see "References", in this appendix. NOTE TMSL (Test and Measurement Systems Language) and HPSL are earlier versions of SCPI. If you have used either of these languages, you probably will have no difficulty using SCPI. If you are familiar with SCPI, but unfamiliar with programming this power supply, read the ’’Language Dictionary" and "Status Reporting" in this appendix.

INTRODUCTION The Agilent 603xA power supplies can now be programmed using either the original language commands (i.e. VSET, ISET, etc.) as documented in Section III of this manual, or the Standard Commands for Programming Instruments (SCPI) as documented in this appendix. Local operation, analog remote programming, and all original language commands remain exactly the same except for the following: • When using SCPI commands, the GP-IB parallel poll interface function (PP) is not implemented by the Agilent 603xA power supplies. • When using the SCPI commands, the Foldback key on the front panel of the Agilent 603xA power supplies will toggle overcurrent protection on and off. Refer to CURR:PROT:STAT in the "Language Dictionary" for more details. Note that all existing software written in the original language commands will still execute correctly with the new 603xA power supplies. LANGUAGE SWITCHING Both the original language commands (COMP for compatibility) and SCPI/TMSL commands are contained in ROM. Individually, either may be used to program the power supply. Two commands have been added to both languages to let you switch from one language to the other, and also query the power supply to determine the active language. SYSTem:LANGuage < TMSL/COMP > SYSTem:LANGuage? For Agilent 603xA power supplies, the original language commands (ARPS) are described in Section III of this manual. For information about the SYST:LANG command as well as the other SCPI commands, refer to the "Language Dictionary’’ in this appendix. When shipped from the factory, Agilent 603xA supplies are set to operate using the original ARPS language commands ...
