Introduction
1.1 SystemOverview
PULSE Vehicle Pass-by systems are customizable PULSE systems with functionality
provided by dedicated hardware and software specifically designed for pass-by
measurements.
The system is built around two basic units:
•GroundStation
• Vehicle Station

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.

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.
1.3 HowtoUsethisManual
This manual covers the installation and setup of PULSE Vehicle Pass-by System for
PULSE, version 19 and above.
From PULSE 19, the Vehicle Pass-by System provides two configuration solutions:
• Ground Station only configuration, defined as
Standard mode in the Pass-by
software
• Ground Station + Vehicle Station configuration, defined as
Multivehicle mode in
the Pass-by software
The manual is designed to give you a complete item overview per configuration prior to
providing step-by-step installation instructions:
•Chapter 2: Provides an overview of the parts used in a Ground Station only
configuration
•Chapter 3: Provides connection and installation instructions for a Ground Station
operation alone
•Chapter 4: Provides an overview of the parts used in a multi-vehicle configuration,
which includes both a Ground Station and Vehicle Station
•Chapter 5: Provides connection and installation instructions for a multi-vehicle
configuration
•Chapter 6: Provides connection and installation instructions for a wireless LAN
system, for transfer of data from the Ground Station to the Vehicle Station in a multi-
vehicle configuration
•Chapter 7: Provides tips and tricks to solve the most common problems during
setup
•Chapter 8: Provides quick instructions on how to set up a configuration – with both
hardware and software
