1 Introduction ABOUT THIS GUIDE This guide provides remote programming information for the following series of GPIB programmable power supplies: • AGILENT Series 664xA, 665xA, 667xA, and 668xA You will find the following information in the rest of this guide: Chapter 2 Chapter 3 Chapter 4 Chapter 5 Appendix A Appendix B Introduction to SCPI messages structure, syntax, and data formats. Examples of SCPI programs. Dictionary of SCPI commands. Table of programming parameters.
PREREQUISITES FOR USING THIS GUIDE This organization of this guide assumes that you know or can learn the following information: 1. 2. 3. 4. 5. 6. How to program in your controller language (Agilent BASIC, QUICKBASIC, C, etc.). The basics of the GPIB (IEEE 488). How to program I/O statements for an IEEE 488 bus instrument. From a programming aspect, the power supply is simply a bus instrument. How to format ASCII statements within you I/O programming statements.
2 Remote Programming GPIB Capabilities Of The Power Supply All power supply functions except for setting the GPIB address are programmable over the IEEE 488 bus (also known as the General Purpose Interface Bus or "GPIB"). The IEEE 488.1 capabilities of the power supply are listed in the Supplemental Characteristics of the Operating Guide. The power supply operates from a GPIB address that is set from the front panel (see System Considerations at the end of this chapter).
SCPI Messages There are two types of SCPI messages, program and response. • A program message consists of one or more properly formatted SCPI commands sent from the controller to the power supply. The message, which may be sent at any time, requests the power supply to perform some action. • A response message consists of data in a specific SCPI format sent from the power supply to the controller. The power supply sends the message only when commanded by a special program message called a "query.
Figure 2-1. Command Message Structure The basic parts of the message in Figure 2-1 are: Message Component Headers Header Separator Data Data Separator Message Units Message Unit Separator Root Specifier Query Indicator Message Terminator Example VOLT LEV PROT CURR The colon in VOLT:LEV 4.5 4.8 The space in VOLT 4. 5 and PROT 4. 8 VOLT:LEV 4.5 PROT 4.8 CURR? The semicolons in VOLT: LEV 4. 5; and PROT 4. 8; The colon in PROT 4. 8; : CURR? The question mark in CURR? The (newline) indicator.
Header Convention. In this manual, headers are emphasized with boldface type. The proper short form is shown in upper-case letters, such as DELay. Header Separator. If a command has more than one header, you must separate them with a colon. (VOLT:PROT OUTPut:PROTection:CLEar) Optional Headers. The use of some headers is optional. Optional headers are shown in brackets, such as OUTPut[:STATe] ON.
Figure 2-2. Partial Command Tree Active Header Path In order to properly traverse the command tree, you must understand the concept of the active header path. When the power supply is turned on (or under any of the other conditions listed above), the active path is at the root. That means the interface is ready to accept any command at the root level, such as TRIGger or STATus in Figure 2-2.
Note The SCPI parser traverses the command tree as described in Appendix A of the IEEE 488.2 standard. The "Enhanced Tree Walking Implementation" given in that appendix is not implemented in the power supply.
Class Current Amplitude Time Expanded decimal format that includes , MIN and MAX. Examples: 273 273. 2.73E2 MAX. MIN and MAX are the minimum and maximum limit values that are implicit in the range specification for the parameter. Table 2-2.
Controlling Output Important The power supply responds simultaneously to both digital and analog programming inputs. If it is receiving an input over the GPIB and a corresponding input from the front panel (and/or from the analog programming port), the power supply output will be the algebraic sum of the inputs. Programming Voltage and Current The following statements program both voltage and current and return the actual output from the sense terminals: OUTP OFF VOLT 4.
Saving and Recalling States You can remotely save and recall operating states. See *SAV and *RCL in "Chapter 3 - Language Dictionary" for the parameters that are saved and recalled. Note When you turn the power supply on, it automatically retrieves the state stored in location 0. When a power supply is delivered, this location contains the factory defaults (see *RST in "Chapter 3 - Language Dictionary"). OUTP OFF;VOLT:LEV 6.5;PROT 6.
Note The last query string can be handled without difficulty. However, should you request too many queries, the system may return a "Query DEADLOCKED” error (-430). In that case, break the long string into smaller parts. Programming the Digital I/O Port Digital control ports 1 and 2 are TTL outputs that can be programmed either high or low. Control port 3 can be programmed to be either a TTL input or a TTL output.
Action Press Press new address keys Press Display Shows Current address New address replaces numbers on the display Display returns to meter mode If you try to enter a forbidden number, ADDR ERROR is displayed.
DOS Drivers Types of Drivers The Agilent 82335A and National Instruments GP-IB are two popular DOS drivers. Each is briefly described here. See the software documentation supplied with the driver for more details. Agilent 82335A Driver. For GW-BASIC programming, the GPIB library is implemented as a series of subroutine calls. To access these subroutines, your application program must include the header file SETUP.BAS, which is part of the DOS driver software. SETUP.

3 Language Dictionary Introduction This section gives the syntax and parameters for all the IEEE 488.2 SCPI commands and the Common commands used by the power supply. It is assumed that you are familiar with the material in "Chapter 2 - Remote Programming". That chapter explains the terms, symbols, and syntactical structures used here and gives an introduction to programming.
Description Of Common Commands Figure 3-1 shows the common commands and queries. These commands are listed alphabetically in the dictionary. If a command has a corresponding query that simply returns the data or status specified by the command, then both command and query are included under the explanation for the command. If a query does not have a corresponding command or is functionally different from the command, then the query is listed separately.
• If *CLS immediately follows a program message terminator (), then the output queue and the MAV bit are also cleared. Command Syntax *CLS Parameters (None) Query Syntax (None) *ESE Meaning and Type Event Status Enable Device Status Description This command programs the Standard Event Status Enable register bits. The programming determines which events of the Standard Event Status Event register (see *ESR?) are allowed to set the ESB (Event Summary Bit) of the Status Byte register.
*IDN? Identification Query Meaning and Type Identification System Interface Description This query requests the power supply to identify itself. It returns a string composed of four fields separated by commas. Query Syntax Returned Parameters Example Related Commands *IDN? Field Information Agilent Technologies Manufacturer xxxxA 4-digit model number followed by a letter suffix nnnnA-nnnnn 10-character serial number or 0 .xx.xx Revision levels of firmware Agilent Technologies,6681,0,A.00.
*OPC? Meaning and Type Operation Complete Device Status Description This query causes the interface to place an ASCII "1" in the Output Queue when all pending operations are completed. Pending operations are as defined for the *OPC command. Unlike *OPC, *OPC? prevents processing of all subsequent commands. *OPC? is intended to be used at the end of a command line so that the application program can then monitor the bus for data until it receives the "1" from the power module Output Queue.
Command Syntax Parameters Example Query Syntax Returned Parameters Related Commands *PSC 0 | 1 | OFF | ON *PSC 0 *PSC 1 *PSC? 0 | 1 *ESE *SRE *PSC causes a write cycle to nonvolatile memory. If *PSC is programmed to 0, then the *ESE and *SRE commands also cause a write cycle to nonvolatile memory. The nonvolatile memory has a finite number of write cycles (see "Table 1-2, Supplementary Characteristics").
*RST Meaning and Type Reset Device State Description This command resets the power supply to a factory-defined state as defined below. *RST also forces an ABORt command. Command State CAL:STAT OFF OUTP[:STAT] OFF CURR[:LEV][:IMM] * OUTP:PROT:DEL * CURR[:LEV]:TRIG * OUTP:REL[:STAT] OFF CURR:PROT:STAT OFF OUTP:REL:POL NORM DIG:DATA 0 TRIG:SOUR BUS DISP[:WIND]:STAT ON VOLT[:LEV][:IMM] * DISP[:WIND]:MODE NORM VOLT[:LEV][:TRIG] * DISP[:WIND]:TEXT VOLT:PROT[:LEV] * INIT:CONT OFF * Model-dependent value.
*SRE Meaning and Type Service Request Enable Device Interface Description This command sets the condition of the Service Request Enable Register. This register determines which bits from the Status Byte Register (see *STB for its bit configuration) are allowed to set the Master Status Summary (MSS) bit and the Request for Service (RQS) summary bit.
Query Syntax Returned Parameters Related Commands *STB? (None) (Register binary value) *TRG Meaning and Type Trigger Device Trigger Description This command generates a trigger when the trigger subsystem has BUS selected as its source. The command has the same affect as the Group Execute Trigger () command.
Description Of Subsystem Commands Figure 3-2 is a tree diagram of the subsystem commands. Commands followed by a question mark (?) take only the query form. Except as noted in the syntax descriptions, all other commands take both the command and query form. The commands are listed in alphabetical order and the commands within each subsystem are grouped alphabetically under the subsystem. Figure 3-2. Subsystem Commands Tree Diagram ABOR This command cancels any trigger actions presently in process.
Current Subsystem This subsystem programs the output current of the power supply. CURR CURR:TRIG These commands set the immediate current level or the pending triggered current level of the power supply. The immediate level is the current programmed for the output terminals. The pending triggered level is a stored current value that is transferred to the output terminals when a trigger occurs.
DIG:DATA This command sets and reads the power supply digital control port when that port is configured for Digital I/O operation. Configuring of the port is done via an internal jumper (see Appendix D in the Operating Guide). The port has three signal pins and a digital ground pin. Pins 1 and 2 are output pins controlled by bits 0 and 1. Pin 3 is controlled by bit 3 and can be programmed to serve either as an input or an output. Pin 4 is the digital ground. Bit position 2 normally serves as an output.
DISP:MODE Switches the display between its normal metering mode and a mode in which it displays text sent by the user. The command uses the character data format. Command Syntax Parameters *RST Value Examples Query Syntax Returned Parameters Related Commands DISPlay[:WINDow]:MODE NORMalITEXT NORMal | TEXT NORM DISP:MODE NORM DISPLAY:MODE NORMAL DISPLAY:WINDOW:MODE TEXT DISPlay[:WINDow]:MODE? NORMAL or TEXT DISP DISP:TEXT *RST DISP:TEXT Allows character strings to be sent to display.
Initiate Subsystem This subsystem enables the trigger system. When a trigger is enabled, an event on a selected trigger source causes the specified trigging action to occur. If the trigger subsystem is not enabled, all trigger commands are ignored. If INIT:CONT is OFF, then INIT enables the trigger subsystem only for a single trigger action. The subsystem must be enabled prior to each subsequent trigger action. If INIT:CONT is ON, then the trigger subsystem is continuously enabled and INIT is redundant.
OUTP:PROT There are two output protection commands that do the following: Clears any OV (overvoltage), OC (overcurrent, unless set via external voltage control),OT OUTP:PROT:CLE (overtemperature), or RI (remote inhibit) protection features. After this command, the output is restored to the state it was in before the protection feature occurred.
OUTP:REL:POL Do not install or program the Agilent Relay Accessories if the power supply maximum output current rating (see Table 3-1) exceeds the contact ratings of the relay. This command is valid only if the power supply is configured for the optional relay connector. Programming NORMal causes the relay output polarity to be the same as the power supply output. Programming REVerse causes the relay output polarity to be opposite to that of the power supply output.
STAT:OPER:COND? This query returns the value of the Operation Condition register. That is a read-only register which holds the real-time (unlatched) operational status of the power supply. Query Syntax Parameters Examples Returned Parameters Related Commands STATus:OPERation:CONDition? (None) STAT:OPER:COND? STATUS:OPERATION:CONDITION? (Register value) (None) STAT:OPER:ENAB This command and its query set and read the value of the Operational Enable register.
STAT:PRES This command sets all defined bits in the Status Subsystem PTR registers and clears all bits in the subsystem NTR and Enable registers. STAT:OPER:PTR is set to 1313 and STAT:QUES:PTR is set to 1555.
Command Syntax Parameters Suffix Default Value Examples Query Syntax Returned Parameters Related Commands STATus:QUEStionable:ENABle 0 to 32727 (None) 0 STAT:QUES:ENAB 20 STAT:QUES:ENAB 16 STATus:QUEStionable:ENABle? (Register value) STAT:QUES? STAT:QUES NTR/PTR Commands These commands allow you to set or read the value of the Questionable NTR (Negative-Transition) and PTR (PositiveTransistion) registers.
SYST:LANG This command switches the interface between its SCPI (TMSL) command language and its compatibility language. The compatability language is provided for emulation of older power supply systems and is described in Appendix B. Sending the command causes: • • The alternate language to become active and to be stored in nonvolatile memory. The power supply to reset to the state stored in Location 0.
TRIG:SOUR This command selects the trigger source. Since the power supply has no other trigger source than the GPIB bus, this command need not be used. It is included in the command set to provide programming compatibility with other instruments (such as the Agilent Electronic Load family) that may have more than one trigger source.
VOLT:PROT This command sets the overvoltage protection (OVP) level of the power supply. If the output voltage exceeds the OVP level, then the power supply output is disabled and the Questionable Condition status register OV bit is set (see "Chapter 4 Status Reporting"). An overvoltage condition can be cleared with the OUTP:PROT:CLE command after the condition that caused the OVP trip is removed. The OVP always trips with zero delay and is unaffected by the OUTP:PROT:DEL command.

4 Status Reporting Power Supply Status Structure Figure 4-1 shows the status register structure of the power supply. The Standard Event, Status Byte, and Service Request Enable registers and the Output Queue perform standard GPIB functions as defined in the IEEE 488.2 Standard Digital Interface for Programmable Instrumentation. The Operation Status and Questionable Status registers implement status functions specific to the power supply.

Device-dependent error. 4 5 7 EXE CME PON Execution error. Command error. Power on.
Questionable Status Group Register Functions The Questionable Status registers record signals that indicate abnormal operation of the power supply. As shown in Figure 4-1, the group consists of the same type of registers as the Status Operation group. The outputs of the Questionable Status group are logically-ORed into the QUES(tionable) summary bit (3) of the Status Byte register.
STATUS BYTE REGISTER This register summarizes the information from all other status groups as defined in the "IEEE 488.2 Standard Digital Interface for Programmable Instrumentation" standard. The bit configuration is shown in Table 4-1. The register can be read either by a serial poll or by *STB?. Both methods return the same data, except for bit 6. Sending *STB? returns MSS in bit 6, while poring the register returns RQS in bit 6.

Comment Allows a positive transition at the CC input (bit 10) to be latched into the Status Event register. 1 Allows the latched CC event to be summed into the OPER summary bit. Enables the OPER summary bit from the Status Byte register to generate RQS.
SCPI Command Completion SCPI commands sent to the power supply are processed either sequentially or in parallel. Sequential commands finish execution before a subsequent command begins. A parallel command can begin execution while a preexisting command is still executing (overlapping commands). Commands that affect trigger actions are among the parallel commands.

B Compatibility Language The Agilent Series 664xA, 665xA, 667xA, and 668xA Power Supplies are programatically compatible with the Agilent 603xA Series AutoRanging Power Supplies (ARPS). This means that you can program the Agilent 664xA, 665xA, 667xA, and 668xA supplies over the GPIB using the ARPS commands. Software that you have written for the autoranging power supplies can also be adapted to program the above supplies.
