03 | Keysight | N3300 Series DC Electronic Loads - Data Sheet
Design a system to test a variety of products:
This series consists of 2 mainframes and 6 modules. The N3300A mainframe is full rack
width. It has 6 slots. The N3301A mainframe is half rack width. It has 2 slots. Any
assortment of the 6 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 configured 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
additional 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 programming and monitoring ports for those
applications that utilize nonstandard 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 Keysight Technologies, Inc. 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 integrate 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 to 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 N3300 electronic loads, all outputs can be measured simultaneously.
Alternatively, multiple single output power sources can be tested simultaneously.
Measure voltage and current simultaneously:
The N3300 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 accurate a picture of momentary power.
