The Complete ac Power
Test Solution
Since your product will have to
operate in the real world of unpredictable ac power, you need to
design and verify its correct operation under a wide range of ac power
inputs. Brownouts, dropouts, sags,
and other irregularities are not
unusual in many communities
today. Agilent ac sources have the
features needed to easily accomplish this test goal either in an R&D
environment or on the manufacturing test floor. If you plan to sell your
products in a worldwide market,
you will also need to test them at
the line voltages and frequencies
that they will eventually operate at.
There is also additional testing
needed to meet regulatory requirements for sale into some countries.
Agilent ac sources offer a complete
solution for ac power testing, helping you to simplify this important
task. These instruments combine
the features of a power amplifier
and arbitrary waveform generator
to give you the ability to do all of
the tests that you need. There are
many standard preprogrammed
waveforms, or you can use the
transient generation system to simulate sophisticated and repeatable
ac line disturbances. dc power can
also be generated, either as a dc
offset or as a pure dc signal.
Powerful Built-in
Measurement Capabilities
Agilent ac sources have extensive
16-bit precision measurement
capabilities which would normally
require a number of complex
measurement instruments, including a DMM (digital multimeter),
oscilloscope, power analyzer, and
harmonic analyzer. The precision
measurements include:
• rms, dc, ac + dc voltage
and current
• peak voltage and current
• real, apparent, and
reactive power
• harmonic analysis of voltage and
current waveforms providing
amplitude and phase up to the
50th harmonic
• THD (total harmonic distortion)
• Triggered acquisition of digitized
voltage and current
Using the measurement capabilities
of an Agilent ac source simplifies
your test setups and helps you
obtain accurate data quickly.
Dual Power Analyzer
Option 020
The powerful built-in power meter/
analyzer in Agilent ac sources
provides everything that you need
to make ac measurements at the ac
input to your DUT. For many test
scenarios, this is the extent of the
ac analysis required.
Some test scenarios, however,
require ac measurements to be
made at both the ac input and the
ac output of the DUT. Option
020 provides an additional power
analyzer, complete with a precision
current shunt, which can be
connected anywhere you need it.
This second analyzer can even be
used for tests where the ac source
is not providing power, thus
expanding the usefulness of this
instrument to many more test
configurations. The additional
analyzer is equivalent in specifications and capabilities to the standard analyzer.

Using the dual power analyzer
option instead of an additional
power analyzer instrument externally is more than just convenient.
Measurements on all four measurement channels (ac source output
voltage and current, and dual power
analyzer voltage and current inputs)
are inherently synchronized with
the ac source output waveform.
This precision would be difficult
to achieve using separate measurement instruments.
Examples Dual Power Analyzer
Applications
• Complete testing of
uninterruptible power
sources (UPS)
• Efficiency testing of
dc power supplies
• Efficiency testing of
ac power sources
• Efficiency testing of transformers
• Safety testing of transformers
• Line disturbance and brownout
testing of dc power supplies
• Line disturbance and brownout
testing of ac power sources
• Sleep mode current monitoring
• Independent power analyzer
Sleep Mode Current Monitoring
Many electronic products have
power-saving or sleep modes. In
this mode, the device draws only
enough power to be able to recognize a “wake-up” signal, and then
execute a smooth “wake-up”. The
power drawn in this mode is a critical parameter, and the ability to
accurately monitor it is important.
The accessory precision current
shunt that is supplied with option
020 is mounted in such a way to
make it easy for you to replace it
with a precision resistor of your
choice. By doing this, you can
configure the system to accurately
monitor extremely low currents.
This provides an easy way for you
to profile the current draw in all
modes of your product’s operation.
Since Agilent 6811B-6813B ac
sources produce dc power as well
as ac power, portable battery operated products can also be tested
with this configuration.
UPS (uninterruptible
power source) T esting
The Dual Power Analyzer Option
provides many important benefits
for UPS testing. Since the key to
correct UPS operation is having the
output react properly to changes on
the input, being able to monitor the
output relative to the input simplifies testing. For example, commands
are available to enable calculation
of UPS transfer time, and the phase
difference between the UPS input
and output voltage. Agilent ac
sources also have programmable
output impedance, enabling the
UPS designer to verify product
stability over a wide range of ac
line impedance.
Free Graphical User
Interface (GUI)
When you need to run a variety of
tests, study the results carefully,
and then run more tests with slightly
varied conditions, writing computer
programs using the extensive SCPI
command set may seem burdensome.
This is when you should download
the latest copy of the Free Agilent ac
Source Graphical User Interface
from www.agilent.com.
The Agilent ac source GUI makes it
quick and easy to set the output of
your Agilent ac source, be it from a
stored waveform or with a waveform
that you create using your mouse.
The GUI also allows you to see the
output of the ac source in graphical
form, save the results, or dump them
directly into a Microsoft Excel file.
Microsoft Excel Link
The direct Excel link feature was
recently added to meet the current
needs of R&D engineers. It makes
it easy to keep the results of many
tests, and makes them easily retrievable. With it, the test records resulting from changing conditions can
be kept in one place and easily
compared.
Access to raw data often helps in
fully understanding test results. For
example, small local peaks may not
be evident in processed data. V, I
and phase results from harmonic
measurements are particularly
susceptible to not showing the
complete story in a graphical
representation.

capabilities that can help an engineer gain the fullest understanding
from the test data.
Test Suite for Avionics Equipment
Agilent ac sources are well suited for
testing equipment intended for use
in the avionics industry which operate at nominally 400 Hz. One of the
special requirements that many
manufacturers in this industry must
concern themselves with is testing to
meet RTCA DO-160 standards.
These standards involve both ac and
dc immunity tests. The Agilent ac
source GUI includes a section devoted to these tests. By using this tool,
you can quickly step through the
required set-ups with confidence.
Extensive protection to
prevent load damage
In addition to overcurrent,
overvoltage, overpower and
overtemperature protection, the
6800 series offers output
disconnect relays and remote
inhibit capability (quickly
disabling the output of the ac
source via a TTL signal) to
protect the device under test.
The 6800 series is backed by a threeyear warranty and Agilent’s worldwide network of support and service
centers.
Application info
The 6800 series can help you test
and improve your products.
You can easily perform:
1. Static testing–generating and
measuring voltage, frequency,
and line current for meeting
worldwide specifications.
2. Dynamic testing–generating
ac line transients for limit
testing and design verification.
3. Specialty testing–measuring
current harmonic content
and creating custom ac power
waveforms (such as a combined
ac + dc signal to simulate a
telephone ring).
4. Precompliance regulatory
testing–measuring current
harmonics, voltage fluctuations
and flicker emissions and
generating voltage and frequency
disturbances and interharmonics
to determine product immunity.
Development engineers and test professionals in a wide variety of industries use ac power source/analyzers.
