The Agilent Electronic Load Family offers the power
supply tester the solution for many of the tests that
must be performed. For bench or system applica-
tions in large or small scale testing environments,
Agilent Electronic Loads provide high quality and
reliability with superior performance, features, and
documentation. This will make power supply test
system configuration easier, measurement proce-
dures repeatable, and operating environments safer.

The Agilent 6060A 300 Watt and 6063A 240 V Single
Input DC Electronic Load provide many features
that are fully programmable in CC, CV, or CR mode.
For measurements that require step load changes,
the 6060A and 6063A contain a transient generator
that has a minimum risetime of 12 microseconds.
This allows for load transient response testing of
high performance linear (series regulated) power
supplies as well as switching power supplies. In
addition, the duty cycle and frequency of the tran-
sient generator can be fully controlled using the
front panel, or via programming through the built-
in GPIB.

Synchronizing the measuring instruments in a
power supply test system is essential to retrieve
valid test data. The 6060A and 6063A can generate
triggers that can externally trigger a DMM, digital
oscilloscope, or wattmeter to take a measurement
as the load changes according to the testing goals.
The 6060A and 6063A can also change in response
to external triggers from other test equipment.

For testing multiple output power supplies, Agilent
offers the 6050A 1800 Watt Load Mainframe. This
product provides an economical alternative to the
6060A and 6063A for large scale testing environ-
ments. It has six slots which can be user-configured
up to 1800 Watts with the Agilent Electronic Load
Modules—the 60501A 150 Watt Module, the 60502A
300 Watt Module, the 60503A 240 Volt Module, and
the 60504A 600 Watt Module. The 6050A provides
all of the features of the 6060A and 6063A.

The Electronic Load Family provides “One Box”
solutions for system applications. These loads con-
tain a DMM and precision current shunt for voltage,
current, and power readback via the built-in GPIB.
In addition, Agilent Electronic Loads contain a
transient generator, provide status readback, and
have voltage and current programmers that reside
in the box. This eliminates the need for external
DMMs in many power supply test applications, and
therefore saves rack space and additional test 
system costs.

For reliable and safe operation, Agilent Electronic
Loads offer full protection against overvoltage, over-
current, overpower, overtemperature, and reverse
polarity conditions. The reliability of Agilent Elec-
tronic Loads are backed by a standard three year
warranty. The reliability, performance, and features
of the 6060A, 6050A, 60501A, 60502A, 60503A, and
60504A, combined with competitive prices, make
these products an optimum solution for power 
supply testing applications.
