If you are a first-time user, start with this manual, paying particular attention to Chapter 2. After installation (Chapter 3), read Chapter 4 to learn front-panel operation. Programming users should then read Chapter 5 before going to the Programming Reference Guide. Experienced programming users will probably refer only to the Programming Reference Guide.

1 General Information What’s In This Manual This manual applies to both the Agilent 6050A and Agilent 6051A Electronic Load mainframes. The two mainframes are functionally identical, but the Agilent 6051A is a half-rack width unit, with only two slots for load modules. Most of the information given in this manual applies to both mainframes. Where differences occur, information specific just to the Agilent 6051A is given in parentheses following information that applies only to the Agilent 605

Safety Requirements This product is a Safety Class 1 instrument, which means that it is provided with a protective earth ground terminal. This terminal must be connected to an ac source that has a 3-wire ground receptacle. Review the instrument rear panel and this manual for safety markings and instructions before operating the instrument. Refer to the Safety Summary page at the beginning of this manual for a summary of general safety information. Specific safety information is located at approp

2 Operation Overview Introduction The Agilent 6050A and Agilent 6051A Multiple Input Electronic Load Mainframes are used for design, manufacturing, and evaluation of dc power supplies, batteries, and power components. Other applications include use as a power circuit breaker or crowbar, high-current function or pulse generator, fuel-cell and photovoltaic cell test, and de-energizing superconducting magnets. The mainframe contains six (two) slots for load modules. Load modules occup

Front Panel Description The front panel includes a 12-character alphanumeric display, 11 status indicators, and four groups of keypads. Ordinarily the alphanumeric display shows the number of the channel presently under front-panel control, and the input voltage and current of that channel. By using the key you can sequentially display input power, programming error codes, and protection-circuit status. If any protection circuits are active, that status will be displayed first when you use

operation, protection features, and other operating features of the Electronic Load. Extended Power Operation Note: Extended power operation is not available on "B " load modules (Agilent Models 60501B-60507B). In addition, this feature may not be present in "A" modules produced after 1989. The extended power feature allows a module to dissipate considerably more than its nominal power rating in many cases. The primary factor limiting the amount of power that can be dissipated is the tem

When programmed to a mode, a module remains in that mode until the mode is changed or until a fault condition, such as an overpower or overtemperature, occurs. When changing modes, the module’s input is momentarily disabled (non-conducting state) before the new mode is enabled. This insures that there will be minimum overshoots when changing modes. The current, resistance, and voltage mode parameters described in subsequent paragraphs can be programmed whether or not the mode is presently sele

Electronic Load are described later in this chapter. The Electronic Load has a status reporting capability to keep track of pending triggers and other operating conditions. The status reporting capability is described in detail in the Agilent Electronic Loads Programming Reference Guide. Transient Current Level The transient current level can be set at the front panel ( , and ENTRY keys) or via the GPIB (CURR:TLEV command). The transient current level determines the higher current level when

Ranges Resistance may be programmed in any of three overlapping ranges (low, middle, high). The range can be set at the front panel ( , , and ENTRY keys) or via the GPIB (RES:RANG command). Any value in the low range selects the low range. Any value that is within the middle range and above the maximum low-range value selects the middle range. Any value that is within the high range and above the maximum middle-range value selects the high range. Note that the values of the present resistan
