HBM (100pf/1,500Ω) to 8kV
MM (200pf/0Ω) to 1kV
HMM (150pf/330Ω) to 4kV
1 9 user programmed test voltages
1 Tests most device configurations
1 Keypad or computer control
1 Meets (HBM) MIL STD. 883E,
JEDEC 22-A115C
1 Optional Charged Device Model (CDM) Test Fixture to 1kV
Electrostatic discharge (ESD) has become a significant factor contributing to the disruption
of electronic equipment or the premature failure of microelectronic devices in both the field
and during the manufacturing process. Sensitivities below 30V are now common. Since it is
not always possible to control the environment where electronic devices are used or
handled, the burden of product reliability falls upon the manufacturer to design and build
equipment with reduced susceptibility to ESD. The ETS Model 9910 ESD Simulator is a
valuable tool for developing components for use in today’s military, industrial and consumer
electronic applications.
The Model 9910 is a bench top system designed for low pin count devices or small product
testing and is ideal for meeting the latest 2-pin testing requirements.
The Model 9910 Electrostatic Discharge Simulator is a completely integrated microprocessor-based
system used to determine the ESD susceptibility level of electronic devices from ±5V to ±8kV. The optional
Model 9903 Charged Device Model Test Fixture adds CDM testing capability up to ±1kV. This enables the
Model 9910 to meet virtually any ESD susceptibility requirement.
Typical discharge waveforms taken with a Tektronix CT-1 Current Transducer are shown below for Human
Body Model (HBM), Machine Model (MM) and Human Metal Model (HMM) at 4kV, 400V and 4kV

The Model 9910 can be operated either manually via the front panel keypad or switched to computer
control. Serial communication protocol is provided to interface the Simulator with user developed control
software (ETS does not offer software). Voltage is adjustable in 1 Volt increments and up to 9 preset
levels from ±5 to ±8250V that can be programmed by the user.
Two modes of operation are available: A MANUAL mode, where a Discharge is initiated each time the
DISCHARGE button is depressed and an AUTO mode, where the number of discharges (0-99) and the
discharge interval (1-99 sec.) are selected by the user and activated when the DISCHARGE button is
depressed. Typically, each device pin combination is tested at both polarities using 3 discharges at 1
second intervals.
The Model 9910 features selection of built-in HBM, MM or HMM networks. The discharge circuit utilizes
mercury high voltage relays for bounce-free operation.
The Model 9910 interfaces with the Device Under Test (DUT) via a universal holding fixture and
minigrabber leads that enable connection to virtually any device that has accessible contacts. DUT boards
with 40-pin DIP, 16-Pin and 28-Pin SOIC pin configurations, shown below plus custom DUT boards up to
84 pins with manual programming input/output, power and ground pins per specification are available. DUT
boards from the Model 910 can be used with the Model 9910.

Optional Accessories:
Model 9903 Charge Device Model Test Fixture: This userfriendly test fixture enables the user to perform both Induced and
Direct Charge Charge/Discharge CDM functions. It includes a
Magnetic Holding Fixture for precise alignment of the DUT, a 1
Ohm radial resistor for direct connection to an oscilloscope plus
interchangeable spring-loaded discharge pins with flat, cup, and
pointed tips. Gold-plated 4pf ANSI/ESD S5.3.1 verification
modules and JEDEC 6.8pf silver-plated discs mounted on 0.8mm
FR4 dielectric are included.

NOTE: The Model 9903 currently does not meet all verification
module waveform characteristics as specified in ESD and JEDEC
specifications. It is up to the end user to determine if the Model
9903 will meet their specific requirements.

Model 9902 Remote Discharge Probe: This Probe is for those applications where testing off line
from the Model 9910 console is desired such as being added to an automatic pick and place test
set up.
The ETS Model 9902 Remote Discharge Probe operates up to 1000V for HBM and MM discharge
models. The Model 9910 provides the necessary signals and voltages to operate the Probe. It can
also be used as a handheld device or with the addition of remote cables, be attached to an
automatic pick and place test system.
