Fig.1.1 shows an overview of a pass-by test system. The typical configuration is a multi-
vehicle configuration using both the Ground Station and Vehicle Station to acquire and
measure both pass-by and in-vehicle data.
On the Ground Station, PULSE measures all acoustic channels, speed measurements
and triggering signals. Photocells provide measurement triggering and an absolute
position reference for distance calculations.
You can also add the following accessories for optional measurement parameters:
• A digital weather station to measure atmospheric conditions to qualify and
document the measurement
• A 2-channel radio telemetry system for transferring engine speed and/or vehicle
speed from the vehicle
• A speed sensor such as a radar or precision GPS to continuously measure the speed
of the vehicle(s) under test
Pass-by Connection Module WB-3595 in the Ground Station’s front end, powers and
conditions the inputs from the photocells and radar when used.
The Vehicle Station measures in-vehicle data such as engine RPM, vehicle speed if an
on-board speed sensor is available, and other in-vehicle data.
Both stations require a PC to be connected to them to control and operate
measurements using the PULSE Vehicle Pass-by software.
1.2 SystemOperation
During the test, the sound pressure levels are measured by microphones connected to the
Ground Station. The results are calculated and saved at the Ground Station. If there is a
Vehicle Station present, the data from the Ground Station is uploaded to the Vehicle Station.
If the Ground Station is used alone, then it measures all data and calculates the results.
If both a Ground Station and Vehicle Station are used, in-vehicle channels such as engine
speed and throttle position, vehicle speed and any other type of onboard, measured
data are acquired by the Vehicle Station. The Ground Station data is transferred to the
Vehicle Station where it is synchronized and merged with data on the Vehicle Station
directly after each run. The pass-by result is then calculated.
Systems with both Ground and Vehicle Stations transfer data between the PCs using
wireless LAN (WLAN). See Chapter 6 for setup instructions.

CHAPTER1
Introduction 3
1.2.1 MultipleVehicleMeasurements
It may be necessary to let several vehicle exterior noise tests run in parallel. In this case,
a single Ground Station acquires the necessary acoustic and triggering reference data
for all of the vehicles and the relevant run data is merged with the Vehicle Station for each
specific vehicle. This enables several vehicles to share the track and a single system
without interfering with each other while automatically obtaining the correct
measurement results.

and Mic B . Mic A will be the microphone to the left of the start position (facing
forwards), and
Mic B will be the microphone to the right.
3) Arrange the mounted Microphones as required by the test standard in use.
If this is a typical pass-by measurement, the front of the Microphone should be
facing the centre line of the test track and placed 7.5 m (24.6 ft) from it. The centre
line of the Microphone should be 1.2 m (3.9 ft) above the measurement plane
(surface of test track) with the body of the Microphone horizontally mounted.
4) Once positioned, cover the Microphones with the supplied foam Windscreens.
3.2.1 ConnectingOptionalAccessories
ConnectaRadarUnit
1) Connect the radar cable to LEMO input 3 on the front end’s Connection Module. Line
up the red dot on the plug and socket to ensure correct alignment.
Fig.3.4
Connectingtheradarcable
tothefrontend
Note:
Although visually similar, the photocell and radar plugs are different, do not mix
them up as you may damage the plug or connector if you attempt to plug it into the
wrong socket.
2) Position the Radar Unit at least 60 m (196.8 ft) from the test zone, at a height
approximating that of the test vehicle’s leading vertical surface. Ideally, position the
Radar Unit as close to the test track centre line as possible – we suggest a distance
of 1.5 m (4.92 ft) from the centre line.
Note:
It is important that the Radar Unit be positioned to emit parallel to the horizontal
reference plane as this will minimize issues such as theradar beam wandering fromthe
front of the vehicle to the windscreen, resulting in an instantaneous speed change.

3) Aim the radar beam at the centre of the test zone (that is, the intersection of the test
track’s centre line and the line 00´ connecting the Microphones). We recommend
that you use the test vehicle (or another object) as a reference point during setup and
that you aim the Radar Unit at this point.
ConnectaWeatherStation
1) Place the Weather Station in a location away from buildings or other structures that
may effect temperature and windspeed readings (ambient free-field conditions)
and also sufficiently far enough away from the test track so as not to be affected by
the passage of vehicles along the test track.
2) Plug the LEMO to RS-232 connector from the Weather Station sensor into the PoE

ConnectaGroundTemperatureSensor
1) Insert the sensor horizontally in the test track asphalt. If the track is raised you can
drill a hole in the side of the asphalt layer.
2) Slide the sensor in horizontally at a point on the track close to the line 00´ and on the
same side as the Ground Station.
3) Route the sensor cable to so as to avoid being driven over or submerged in water.
4) Place the sensor’s conditioning unit close to the Ground Station and plug it into a
mains socket to power it. Connect the output using a BNC cable to channel 4 on the
front end’s Input Module.
ConnectRadioTelemetryforIn‐vehicleParameters
1) Power the Telemetry Receiver Unit from a 10 – 30 volt supply. This can be the
auxiliary power output at the rear of the front end frame.
2) If you are transferring vehicle speed data from the precision GPS speed sensor, unplug
the short BNC cable that connects the radar output to the Input Module (channel 6)
and plug a BNC cable between the relevant output at the front of the Telemetry
Receiver Unit and the now vacant input channel 6 on the Input Module.
3) Inside of the vehicle, connect the Telemetry Transmitter Unit using the supplied
power cable to the Cigarette Lighter Splitter for power.
4) Connect the Telemetry Transmitter Unit with the supplied cables to the in-vehicle
sensor(s) remembering to keep the channels in the same order as they are
connected on the Telemetry Receiver Unit to the front end’s Input Module.
5) Locate all of the in-vehicle telemetry hardware in a safe and secure fashion within the
vehicle.
For detailed use instructions of the telemetry system, please refer to the KMT product
documentation.
