Dear Customer, |
|
In our ongoing efforts to deliver valuable
and practical solutions to engineers, we are
proud to present another edition of
"applicationXplorer".
Yokogawa instruments not only provide unique
solutions such as power supply efficiency
testing, but also measurement solutions that
meet other challenges facing today's
engineers. |
DLM2000 Series Scope Model Ideal for
Debugging Embedded Systems
|
 From
digital home electronics to automobiles, a
boom has recently occurred in numerous
industries that use embedded systems in
which functionality is achieved through
processors and software. Although much of
the products I/O may be an analog signal
such as from a sensor or voice transducer,
the processor handles the A/D-converted
digital signal. In order to debug these
types of systems, we are now seeing an
increasing need to interpret the digital
signals and confirm the corresponding
action. Therefore, there is an increased
need for a single measurement tool known as
a "mixed signal oscilloscope" that can look
at both signal environments.
Given these requirements, Yokogawa is proud
to introduce the new DLM2000 series of mixed
signal oscilloscopes which are compact and
lightweight, portrait-shaped models with a
modest footprint. The DLM2000 series are
mid-range (500 MHz frequency bandwidth,
maximum sampling rate of 2.5 GS/s) mixed
signal oscilloscopes that come standard with
8-bit logic and offer higher waveform
acquisition rates and data processing
power-with or without the logic display.
Waveform phenomena are intuitively
displayed-brightness corresponds to the
overlapping of sampling points, and the
points are converted to color and displayed
on the XGA resolution wide-viewing angle
LCD.
A powerful set of standard features and
options enable fast R&D and Design
Verification cycles. Whether your product is
analog, digital or bit of both - there is a
DLM2000 model that matches your needs. You
can customize yours too, choosing from
options such as powerful user-defined math,
power analysis, and serial analysis packages
UART, I2C, SPI, CAN & LIN, or super-long
memory, printer, I/O interface, and storage
options. For every engineer and every
budget, there is a DLM2000.

Introducing
the WT500 Mid-Range Power Analyzer
|
 The
WT500 is being added to the Yokogawa
line of Digital Power Analyzers as a new
Mid-Range product. It is positioned as
an upgrade to the WT210 & WT230 Entry
Level products with enhanced features
such as a large Color TFT LCD Display,
single & three-phase models, a basic
accuracy 0.1% of reading, maximum direct
input of 1000 Vrms and 40 Arms, and a
bandwidth of DC, 0.5Hz to 100 kHz.
This new Power Analyzer can be
configured with 1 to 3 totally
independent and isolated input elements
for the simultaneous measurement of DC
and AC signals. Applications for the
WT500 will include inverter testing and
efficiency calculations for
input-to-output power of inverters used
in renewable energy products. A new
Integration function is provided for
Watt-Hour and Amp-Hour measurements that
provides evaluation of both
Charge/Discharge and Bought/Sold power.
Two front panel USB ports are provided
for storing measured data in a CSV
format directly to a USB memory stick.
Communications to a PC is provided by a
standard USB Interface, with options for
GPIB and Ethernet.
An optional Harmonic Analysis function
is available for harmonic component and
THD (Total Harmonic Distortion)
measurements up to the 50th order.
Advanced signal processing circuitry
allows for simultaneous measurement of
harmonic data along with normal power
measurement parameters.
The large bright 5.7 inch color Display
provides a variety of useful display
formats. Numeric data, Waveforms,
Trend, Harmonic and Vector displays are
user selectable. An optional VGA output
is also available.
Yokogawa offers a complete line of
Digital Power Analyzers designed to meet
your application, measurement and budget
requirements.

Application Series: Photovoltaic System Power
Measurement |
Photovoltaic power generation is considered to
be one of the most important renewable energy
resources for the future. The Photovoltaic (PV)
power system requires a high-efficiency DC to AC
inverter that delivers the power to the load and
the grid. This inverter must also have a very
low Total Harmonic Distortion (THD) of the
output waveforms and a high Power Factor.
The Yokogawa precision Power Analyzers provide
the measurement solution required for the
design, development and testing of these
inverters. Since the inverters used in these
systems must have a very high efficiency rating,
extremely highly accurate power measurements
must be made to verify these results. As an
example, the WT3000 Power Analyzer has a basic
power measurement accuracy of 0.02% of reading.
A harmonic analysis function is available which
can calculate the THD as well as the individual
harmonic amplitudes display a harmonic spectrum
and phase vector diagrams. Often it is
important to analyze the Inverter Voltage,
Current & Power on a cycle-by-cycle basis which
can be done in the WT3000.
The Solar Photovoltaic cells used in these
systems must be tested to determine their
electrical characteristics. This electrical
characterization is necessary in order to
determine PV cell efficiency, losses and power
output. The Yokogawa Model GS610 Source Measure
Unit can be used as an electronic load to
characterize the Voltage-Current (V-I)
performance of individual or groups of PV
cells. These tests are typically done at
different light intensities and temperatures.
The GS610 provides various operational modes
such as Continuous, Linear and Log Sweeps and
Program Sweep. The internal memory of the unit
functions as a USB storage device. The V-I
measurements can be stored and retrieved into
the PC simply with the USB interface by dragging
and dropping the file. There is no cumbersome
programming or dedicated software programs
required.

Remote Control of the AQ2201/AQ2202 Frame
Controller |
 Yokogawa's
new remote control software for the AQ2200
family enables new business practices. The
software comes in 2 parts, an upgrade for the
Frame controller to version 08.02 and a remote
control program to load onto your PC.
Once installed the user is provided a Graphical
User Interface that is the same as the front
pane of the Frame Controller. The interface
acts exactly the same as if you are sitting in
front of the control panel. By using the same
image as the local controller, no new training
is needed. This image is the actual controller
image from the remote PC.

Test Tips |
 Do
you have elusive or intermittent electrical
faults?
Do you have symptoms of glitches, drop-outs or
invalid signaling or sequencing?
What about power quality issues such as voltage
sags or surges?
Any engineer who occasionally needs to detect,
measure, and record the presence of intermittent
signals or faults knows how difficult the
troubleshooting process can become. That
difficult process can be lengthy, time-consuming
and take you away from other duties.
When it comes to capturing and documenting these
electrical faults, the Yokogawa
ScopeCorder is your best ally. It is capable of
attended or unattended, triggered or
un-triggered, and simultaneously automated
electrical testing, and data collection. You can
monitor for intermittents for a few
milliseconds, a few days, or for a few months.
The unit features sixteen analog channels and
sixteen additional logic channels, so you see a
lot of signals -- for as long as you need. The
unit can also notify you of fault conditions via
email.
