Model 431 Shielded Bag Test System -
 Description-
The Model 431 Shielded Bag Test System is designed to perform ESD STM11.31 and EIA-541 tests when used in conjunction with a high speed oscilloscope and computer. The system
provides the discharge pulse and the resulting attenuated voltage output for direct connection to a 2-channel oscilloscope for EIA-541 testing, or a current pulse for the ESD STM11.31 test.
The Model 431 consists of an adjustable 800 to 1200 Volt power supply with a 3½ -digit LCD display, 100 pf/ 1500 Ohm HBM network (200 pf/1500 Ohm for EIA-541), a mercury wetted charge/ discharge
relay, capacitive sensor and a controlled force discharge electrode. Adjustable bag insertion stops enable the user to configure the System for different bag sizes per specification. A Tektronix CT-1
current sensor with 500 Ohm resistor, and built-in 100:1 voltage attenuators are standard for interfacing the System with an appropriate user supplied oscilloscope. (50 MHz, 100 MS/s for EIA
-541; 200 MHz, 1GS/s with computer interface for ESD STM11.31.)
Multicolored LED point sources indicate CHARGE,
DISCHARGE and TEST OVER functions. The FUNCTION
switch is used to select either a voltage differential
(EIA-541) or a current pulse (ESD S11.31) measurement.
The discharge is initiated by either a front panel discharge
switch or by a foot operated switch which is convenient
when testing in a humidity chamber.
A computer interface enables the discharge sequence specified in ESD STM11.31 to be automatically controlled by the ETS Test Suite Manager Program. The discharge of the Model 431 meets the requirements of ESD S5.1 “Electrostatic Discharge Sensitivity Testing-Human Body Model.”
Plug-in R/C components allows other networks to be used. Cables are provided for interfacing the Model 431, oscilloscopes and computer parallel port.
The Test Suite Manager Program displays the waveforms, calculates the energy of the discharge pulse induced inside the test bag and
processes the data in accordance with ESD STM 11.31. It also automatically controls the Model 431 and program the oscilloscope.

Model 930D Electrostatic Discharge Simulator
Description-The Model 930D produces ESD pulses from ±500 to ±26kV (Optionally ±30kV). Select
either the 1.5k ohm/ 100pf Human Body Model (HBM) Network, IEC 1000-4-2/801-2 (1991& 1984) or from a variety of automotive, electronic and military plug-in R/C networks.
The Model 930D is composed of a controller and a gun connected by a detachable 12-ft cable. The control unit houses the low voltage power supply with LED status indicators, system timing electronics
, a .5” LED display and controls for the AUTO MODE event counter and a high voltage power supply. In addition, a set of Charge/ Discharge controls are provided for remote operation.
The gun contains the high voltage power supply and high voltage relay plus plug- in resistor and capacitor networks. It incorporates high voltage
ON/OFF, MANUAL/ AUTO and RELAY/AIR discharge controls along with LED status indicators. A ¼-20 threaded hole enables the
gun to be mounted to a tripod.
The system has four modes of operation: AUTO COUNT, FREE RUN, MANUAL and AIR DISCHARGE. Air Discharge and Manual operations are
controlled by the switches on the gun. The Model 930D includes 0.50” diameter elliptical (finger tip) and conical point probe tips, standard banana
jack adapter and a 2-meter ground cable, contained in a sturdy polystyrene carrying case.
