Evaluation of ITS Equipment
쎲 Generation and analysis of RF signals
The RF Signal Generator and the RF Signal Analyzer can evaluate the dedicated short-range communication (DSRC) function required for ITS equipment. To generate
an RF signal using the VG6000 RF Signal Generator, a PC is used first to compile modulation signal data so that the data is compliant with various standards. The
VG6000 RF Signal Generator modulates the data and outputs it. The VN7100 RF Modulation Analyzer down-converts RF signals output from the equipment under
evaluation into baseband signals for analog/digital (A/D conversion), and loads them into the internal memory.

쎲 Evaluation of Internal I2C and SPI Buses for Car Navigation and Audio Systems
The DL9000 Series performs protocol analysis and observation of the signal waveforms of general-purpose I2C and SPI serial data buses, which are widely used as
internal buses for car navigation and audio systems. As the DL9000 Series can simultaneously observe protocol analysis data and waveform signals, it enables users to
quickly troubleshoot and identify malfunctions.
To meet the three essential requirements for automobiles – safety, environmental friendliness,
and comfort – the amount of electronic components in vehicles is increasing at a rapid pace.
In pursuit of better gas mileage, the development of electric vehicles (EVs)
and hybrid electric vehicles (HEVs) is ongoing, as is research into fuels cells,
whose energy density exceeds that of the engines powering EVs and HEVs.
In the meantime, the fields of in-vehicle data communication and computerization
are progressing rapidly as cars are being increasingly equipped with more electrical equipment
for greater comfort and safety. With the aim of supporting future automobile development and evaluation,
Yokogawa Electric offers various categories of measuring instruments in five fields:
“Hybrid EV,” “Fuel cell,” “In-vehicle LAN,” “Vehicle Components,” and “Intelligent Transport System (ITS) equipment.”

We provide a wide variety of test equipment solutions – such as waveform measuring instruments,
power meters, and signal generators – to meet your development and evaluation needs
Hybrid and EV Development
쎲 Motor and inverter I/O efficiency measurements
and harmonic waveform analysis
Highly accurate measurements can be made using the WT3000, which boasts the
world's highest measurement accuracy of ±0.06%. Capable of being equipped with
four input elements, the WT3000 can measure input signals simultaneously with
output signals, and harmonic waves simultaneously with normal waves. In addition,
the WT3000 can be used for the evaluation of inverter/driver conversion efficiency
and pulse width modulation (PWM) signals. (Using the three-phase model, as of August 2006)
쎲 CAN-bus waveform observation and
protocol analysis
The DL750/750P can simultaneously measure multiple signals and display
their waveforms. Based on measurements of signals from up to 16 channels,
motor characteristics such as torque, speed, temperature, and distortion can
be determined. Most notably, the waveform calculation function of the
DL750/750P calculates the sum of instantaneous power values, enabling the
observation of changes in three-phase power values.
The DL9000 with CAN-bus triggers and protocol analysis
functions, captures and displays the physical layer waveforms and
decodes the CAN protocol in real time. Triggers can be set for
specific CAN events or for CAN events in combination with input
signals on other channels (for example a sensor output).

load changes.

and performing integration for each polarity (charge, discharge).

쎲 Simulate voltage change and noise, and measure the results
The GS610 is a highly accurate, programmable voltage/current source with a
measurement function. For example, it can be programmed to output a signal
representing a power supply voltage drop at the startup of an air conditioner, as well as a
signal indicating a spike noise waveform at the startup of a wiper motor. As the GS610
can re-create power supply voltage changes of actual vehicles in a laboratory, a noise
test can be conducted on devices under test without installing them in the vehicle.

For quantitative evaluation of internal loss, the WT1600FC measures the impedance of a

capacity) to a full stack of cells (large capacity). Impedance measurements can be
performed for two channels at one time.
