The following general safety precautions must be observed during all phases of operation, service, and repair of this instrument. Failure to comply with these precautions or with specific warnings elsewhere in this manual violates safety standards of design, manufacture, and intended use of the instrument. Agilent Technologies assumes no liability for the customer’s failure to comply with these requirements.
BEFORE APPLYING POWER.
Verify that the product is set to match the available line voltage and the correct fuse is installed.
GROUND THE INSTRUMENT.
This product is a Safety Class 1 instrument (provided with a protective earth terminal). To minimize shock hazard, the instrument chassis and cabinet must be connected to an electrical ground. The instrument must be connected to the ac power supply mains through a threeconductor power cable, with the third wire firmly connected to an electrical ground (safety ground) at the power outlet. For instruments designed to be hard-wired to the ac power lines (supply mains), connect the protective earth terminal to a protective conductor before any other connection is made. Any interruption of the protective (grounding) conductor or disconnection of the protective earth terminal will cause a potential shock hazard that could result in personal injury. If the instrument is to be energized via an external autotransformer for voltage reduction, be certain that the autotransformer common terminal is connected to the neutral (earthed pole) of the ac power lines (supply mains).
FUSES.
Only fuses with the required rated current, voltage, and specified type (normal blow, time delay, etc.) should be used. Do not use repaired fuses or short circuited fuseholders. To do so could cause a shock or fire hazard.
DO NOT OPERATE IN AN EXPLOSIVE ATMOSPHERE.
Do not operate the instrument in the presence of flammable gases or fumes.
KEEP AWAY FROM LIVE CIRCUITS.
Operating personnel must not remove instrument covers. Component replacement and internal adjustments must be made by qualified service personnel. Do not replace components with power cable connected. Under certain conditions, dangerous voltages may exist even with the power cable removed. To avoid injuries, always disconnect power, discharge circuits and remove external voltage sources before touching components.
DO NOT SERVICE OR ADJUST ALONE.
Do not attempt internal service or adjustment unless another person, capable of rendering first aid and resuscitation, is present.
DO NOT EXCEED INPUT RATINGS.
This instrument may be equipped with a line filter to reduce electromagnetic interference and must be connected to a properly grounded receptacle to minimize electric shock hazard. Operation at line voltages or frequencies in excess of those stated on the data plate may cause leakage currents in excess of 5.0 mA peak.
SAFETY SYMBOLS.
Instruction manual symbol: the product will be marked with this symbol when it is necessary for the user to refer to the instruction manual (refer to Table of Contents) .
Indicates hazardous voltages.
Indicate earth (ground) terminal.
The WARNING sign denotes a hazard. It calls attention to a procedure, practice, or the like, which, if not correctly performed or adhered to, could result in personal injury. Do not proceed beyond a WARNING sign until the indicated conditions are fully understood and met.
The CAUTION sign denotes a hazard. It calls attention to an operating procedure, or the like, which, if not correctly performed or adhered to, could result in damage to or destruction of part or all of the product. Do not proceed beyond a CAUTION sign until the indicated conditions are fully understood and met.
DO NOT SUBSTITUTE PARTS OR MODIFY INSTRUMENT.
Because of the danger of introducing additional hazards, do not install substitute parts or perform any unauthorized modification to the instrument. Return the instrument to an Agilent Technologies Sales and Service Offices for service and repair to ensure that safety features are maintained.
Instruments which appear damaged or defective should be made inoperative and secured against unintended operation until they can be repaired by qualified service personnel.

Each power supply is programmable locally from the front panel or remotely via a rear-panel analog control port.
General Information 17
Operational features include:
■Constant voltage (CV) or constant current (CC) output over the rated output range.
■Built-in overvoltage (OV), overcurrent (OC), and overtemperature (OT) protection.
■Automatic turn-on selftest.
■Pushbutton nonvolatile storage and recall of up to 5 operating states (4 in Series 668xA supplies).
■Local or remote sensing of output voltage.
■Auto-parallel operation for increased total current.
■Series operation for increased total voltage.
■Analog input for remote programming of voltage and current.
■Voltage output for external monitoring of output current.
■User calibration from the front panel.
Front Panel Programming
The front panel has both rotary (RPG) and keypad controls for setting the output voltage and current. The panel display provides digital readouts of the output voltage and current. Other front panel controls permit:
■Enabling or disabling the output.
■Setting the overvoltage protection (OVP) trip voltage.
■Enabling or disabling the overcurrent protection (OCP) feature.
■Saving and recalling operating states.
■Setting the GPIB address.
■Reading GPIB error message codes.
■Calibrating the power supply, including changing the calibration protection password.
Remote Programming
The power supply may be remotely programmed via the GPIB bus and/or from an analog input port. GPIB programming is with SCPI (Standard Commands for Programmable Instruments) commands that make the power supply programs compatible with those of other GPIB instruments. (A software-controlled Compatibility Mode also permits programming in the command set of the Agilent 6030xA Autoranging Series.) In addition to control functions, SCPI programming permits writing to the front panel LCD and complete calibration functions. Power supply status registers permit remote monitoring of the following conditions:
■Overvoltage, overcurrent, overtemperature, and unregulated states.
■Operating mode (constant voltage or constant current).
■State of the RI (remote inhibit) input signal.
■Power-on status (PON).
■Status of the output queue (QYE).
■Pending triggers (WTG).
■GPIB interface programming errors (CME, DDE, and EXE).
■Calibration state (enabled or disabled).
The status registers can be programmed to generate an output fault signal (FLT) upon the occurrence of one or more selected status events.
Analog Programming
The power supply has an analog port for remote programming. The output voltage and/or current of the power supply may be controlled by individual d-c programming voltages applied to this port. The port also provides a monitor output that supplies a d-c voltage proportional to the output current.
18 General Information
Output Characteristic
General
The power supply can operate in either CV (constant voltage) or CC (constant current) over its voltage and current ratings (see Table 1-l). The operating locus is shown by the Output Characteristic Curve in Table 1-2. The operating point is determined by the voltage setting (Vs), the current setting (Is), and the load impedance. Two operating points are shown. Point 1 is defined by the load line cutting the operating locus in the constant-voltage region. This region defines the CV mode. Point 2 is defined by the load line cutting the operating locus in the constant-current region. This region defines the CC mode.
Downprogramming
The power supply can sink current for more rapid down programming in the CV mode. For Series 664xA and 665xA supplies, this capability is defined by the second quadrant area (-Is) of the Output Characteristic Curve. These supplies can sink about 20% of their maximum rated positive output current. For Series 667xA and 668xA power supplies, this is an uncharacterized current-sinking area that provides a limited downprogramming capability.
Tables 1-1 through 1-4 list the specifications and supplemental characteristics for the Series 664xA, 665xA, 667xA, and 668xA power supplies. The organization is as follows:
