1. SmartScan 350/550 Overview
Amber Precision Instruments is an IC, module and system level EMC/EMI evaluation tool
manufacturer. API is equipped with unique combination of IC level and system level expertise
and offers SmartScan as high level solution to EMC/EMI evaluation. Smart Scan is an evaluation
system that pin-points problem spots of a board/system or pins of IC. It offers a wide range of
tools for susceptibility scanning as well as a user oriented intuitive interface, which provides
time and resource saving benefits.
The following technologies are integrated in to the software package, and are described in detail
in the other sections of a corresponding manual:
EMI Scan, ESD Scan, Phase Measurement Scan, Current Spreading Scan, Resonance Scan,
Current Spreading Scan, RF Immunity Scan, and ESM Scan.
2. ESD Scanner Outline
The main role of the ESD (electro-static discharge) scanner is to detect potential failure zones of
a DUT (device under test). It consists of a robotic arm, scanning surface, SmartScan software
package, TLP (transmission line pulsar), and FD (failure detection) module. The ESD scanner
injects a disturbance into the DUT, analyzes the response, and displays the data acquired from
the DUT in visual form superimposed on the DUT itself. Probe movement and data display are
fully automated with proprietary hardware and software.
2.1. Configuration Diagram
Below (Figure 1) is a block diagram of the ESD scanner. The DUT is operating normally while
being scanned over and injected short disturbance pulse by a probe to detect upset and failure.
The FD (failure detection) Module monitors the DUT for upset. Movement of the probe is
automated via a four axis scara robot controlled by SmartScan software.
Collected data is displayed on a monitor and superimposed on the DUT. The result is a visual
display of areas potentially susceptible to ESD events and therefore indicates zones most prone
to failure. The displayed map is then used to identify circuit components and PCB layout
problems that are contributing ESD failure.

2.2. Main Components of ESD Scanner
SmartScan
SmartScan is the proprietary software controlling the hardware components and processing
the collected data.
Probe Movement Mechanism
The attached probe is moved to user-specified probing positions by one four-axis scara robot.
The robot facilities 4 degrees of movement: along x-axis, y-axis, z-axis, and 360° rotation
(both clockwise and counterclockwise directions).
Probe
The probes function by inducing an ESD disturbance pulse in the established DUT. Four
different probe types are available to inject magnetic (H) or electric (E) fields in directions of
x, y and z movement. The commercially available probe types are: Hz, Hx/y, Ez, and Ex/Ey.

9
Cameras
A high resolution USB camera is attached to the robot and used to take pictures of the DUT.
The detected electromagnetic emission intensity is color coded and then superimposed on the
picture taken by the USB camera prior to the test.
RF Amplifier
In cases where signals are too weak to be detected directly by the spectrum analyzer, an
external RF amplifier may be required.
FD Module
FD Module is used to analyze the feedback from the DUT in order to detect an upset or
failure. It is also used to operate variety of hardware, such as relays, call box, and power
supply for DUT rebutting in order to return a DUT in its normal operating mode after failure.
TLP
The TLP box produces a very fast pulse that emulates the fields produced by an ESD event.
3. Understanding the Terminology
TERM
DESCRIPTION
SmartScan
A software package that allows user to set
scanning area parameters, create a test
scenario, identify the location and number of
test points, control data collection, facilitates
interpretation and visualization, and provides
a built in report generation functionality.
SmartScan Workspace
A file that contains many projects.
SmartScan Project
It contains the information about the test
performed on the DUT, together with
analyzed data.
FD Module
A Failure Detection module (software)
integrated into SmartScan V5.0 that is
responsible for failure detection and DUT
control for ESD Immunity test.
FD Project
A project that contains specific FD and DUT
control settings for FD Module.

10
Group
Set of channels that describes a single type of
failure.
Analog Channel
An analog (optical, audio, microphone) input
on the Failure Detection Box.
Digital Channel
A digital input on the Failure Detection Box.
Macros
A sequence of actions required to control
either DUT or failure detection.
4. ESD Scanner Operation Procedures
The hardware set up should be accomplished at this point, e.g. the probe is attached to the robot;
amps, cables and instrument are connected. Operation procedures are described in the order of
normal operation sequence.
4.1. Create "Workspace" and "Project"
As user opens SmartScan V5.0 ( ) , following window with "Workspace Explorer" docking
pane on left and "Wizard" pane on right, pops up. Docking panes can be selected by user as
shown in Figure 2.
