Agilent dc Electronic Loads

Agilent dc electronic loads are ideal for the test and evaluation of
dc power sources and power components and are well-suited for
applications in areas such as manufacturing, research and devel­opment, and incoming inspection.

The Agilent One-Box Solution

Agilent single-input loads and load mainframes are equipped with
standard GPIB interfaces. This built-in IEEE-488 interface allows
complete control of all load functions as well as readback of input
voltage, current, power, and detailed operating status. Each stand
alone load or load module also includes programming inputs that
allow control of load current via an analog voltage. Other system
features contributing to the one-box solution concept are internal
voltage and current monitors and an internal transient generator
with programmable amplitudes, frequency, duty cycle, and slew
rate. The one-box solution saves space, cost, and time while
making these dc electronic loads easy to integrate into automated
test systems.

Agilent dc electronic loads are optimized to address a broad
range of dynamic loading applications. They are specifically
designed for stability in applications where fast transients are
applied to the load inputs, such as during dc power supply startup
characterization or transient response testing. Dynamic load per­formance can be further tailored to specific application needs with
the programmable slew rate feature.

Fully-Compatible Operation

These dc electronic loads respond to instructions from the
industry-standard SCPI command set. Moreover, the features of
these dc electronic loads are fully compatible with one another.
For example, test programs developed for 6060B 300 W single­input electronic load or 60502B 300 W single-input load module
are interchangeable.

The dc electronic load family is also fully compatible with the
59510A relay accessory (see page 33). The 59510A provides physi­cal isolation of the dc electronic load from the device under test or
any other test instrument by switching power and sense leads.
Capable of switching up to 60 A and 200 Vdc, the 59510A
can be controlled by rear-panel signals on the electronic load.

Battery T esting

The 6050A Option J10, 6051A Option J10 and 6060B Option J10
electronic loads are modified for battery testing. These products
provide tri-level pulse loading, to simulate accurate conditions on
batteries. They also feature a programmable minimum battery
voltage threshold (measured at load terminal). If the voltage of the
battery under test falls below this threshold, the load will automat­ically turn off.

System or Manual Applications

Agilent dc electronic loads are equally suitable for manual use on
the bench. The front-panel LCD meters indicate voltage, current,
and power readings. The full-function front-panel keypad allows
easy, repeatable, and reliable control of the load when it is used
manually. Six volatile user-definable states allow you to easily
save settings for later recall. An additional user-definable power ­up state allows you to define settings that are remembered when
the unit is switched off and then recalled when it is switched
on again.

Specifying System Performance

Because Agilent electronic loads feature an integrated GPIB
programmer, pulse generator , current shunt, DMM, and cabling,
their performance is specified as a system. Specifications cover all
the integrated functions as one unit, which eliminates the need to
calculate the actual performance of the automated test system
based on each component’s specification. The one-box solution
makes the integration and documentation of your test system
fast and easy.

Single-Input Products

The 6060B and 6063B are single-input loads with standard rear­panel inputs. They are also available with optional front-panel
inputs in addition to the rear-panel inputs. Front-panel inputs
(Option 020) make input connections to the electronic load
convenient for bench applications. These front-panel terminals
are capable of handling the entire current rating of the load and
can accept wire gauges up to AWG#4 (22 mm

2

). They require no

tools to tighten, making the connections quick and easy.

Mainframe Products

The 6050A 1,800-W and 6051A 600-W electronic load mainframes
accept the user-installable load modules for easy system config­uration and future reconfiguration, if desired. The 6050A holds up
to six 60501B, 60502B, and 60503B load modules, or three 60504B
and 60507B load modules, allowing up to 1,800 W of total maxi­mum power. The 6051A holds up to two 60501B, 60502B, 60503B
modules, or one 60504B or 60507B module allowing up to 600 W
of total maximum power. One GPIB address is all you need for
complete control and readback of all load modules within a single
mainframe.

Operating Agilent Loads Below the Minimum Input
Voltage Specification

Agilent electronic loads meet all specifications when operated
above 3.0 V; however , the dc operating characteristics also extend
below this minimum-input voltage for static tests. Because of the
FET technology used in the power input circuits, these electronic
loads have a low minimum- input resistance allowing them to sink
high currents even at low voltages.

Figure A shows the operating range of a typical Agilent dc
electronic load. Notice that low-voltage operation, down to zero
volts, is possible at correspondingly-reduced current levels,
depending on the minimum resistance of the load. These electronic
loads, therefore, can be used in many applications that previously
required zero-volt loads.
