Design a system to test a
variety of products
This series consists of 2 mainframes
and 5 modules. The N3300A main-
frame is full rack width. It has
6 slots. The N3301A mainframe
is half rack width. It has 2 slots.
Any assortment of the 5 different
modules can be configured into
these mainframes, up to the slot
capacity. The N3302A (150 watts),
N3303A (250 watts), N3307A
(250 watts) and N3304A (300 watts)
each require one slot. The N3305A
(500 watts) and the N3306A
(600 watts) each require 2 slots.
The electronic load can be con-
figured to supply exactly what
you need now, and this modular
design also allows for easy future
reconfiguration.
Test high current power supplies
Electronic load modules can be
operated in parallel to provide
addition current sinking capability.
Control the electronic load
how you want to
GPIB,RS232,andmanualuseof
the front panel all provide complete
control of these electronic loads.
There are also analog program-
ming and monitoring ports for
those applications that utilize
non-standard interfaces, require
custom waveforms, or utilize
process control signals. Custom
waveforms can also be created
by downloading a “List” of load
parameters. In addition, there is a
built-in transient generator, which
operates in all modes.
Quickly create powerful and
consistent software
All Agilent Technologies electronic
loads use the SCPI (Standard
Commands for Programmable
Instruments) command set. This
makes learning the commands easy,
because they are the same format
as all other SCPI instruments. The
resulting code is virtually self-
documenting, and therefore easier
to troubleshoot and modify in the
future. Plug-n-Play drivers are
also available to help you to inte-
grate the loads into your standard
software packages.
Make Measurements
Easily and Accurately
The 16-bit voltage, current and
power measurement system provides
both accuracy and convenience. The
alternative is using a dmm (digital
multimeter)andMUX(multiplexer)
along with a precision current shunt
and a lot of extra wiring. Avoiding
this complexity increases system
reliability and makes the system
easier to design and support. Current
measurements in particular are
more consistently accurate using
the electronic load’s internal system,
because the wiring associated with
an external precision current shunt
may pick up noise.
Measure with all load
modules simultaneously
Testing multiple-output DC power
supplies and DC-DC converters
can be very time consuming if each
output must be tested sequentially.
If measurements are being made
throughaMUXusingoneDMM,
this is what will happen. Using the
built-in measurement capabilities
of the N3300A electronic loads, all
outputs can be measured simultane-
ously. Alternatively, multiple single
output power sources can be tested
simultaneously.
Measure voltage and
current simultaneously
The N3300A measurement system
has individual but linked current
and voltage measurement systems.
This means that voltage and current
measurements are taken exactly
simultaneously, which gives a true
picture of the power supply under
test’s output at a particular moment
in time. Some other electronic loads
which feature internal measurement
systems actually take current and
voltage measurements sequentially,
and therefore do not give as accu-
rate a picture of momentary power.
Observe transient behavior
using waveform digitization
Transient response and other
dynamic tests often require an
oscilloscope. The N3300A has a
flexible waveform digitizer with a
4096 data point buffer for voltage
and a 4096 data point buffer for
current. Under many circumstances,
this internal digitizer will be ade-
quate for power supply test needs.
Current and voltage are digitized
simultaneously, and the sampling
rate and sample window are pro-
grammable. Some analysis functions
are provided, including RMS, max
and min.
