tween the system and the user. Designed with

the research and manufacturing environments in

mind, the GUI allows the user to configure and

monitor all samples under test. Created with Na-

tional Instruments LabWindows under Windows

95, the control screens appear like the front panel

of a test instrument. Using a mouse and key-

board, the software is intuitive and easy to learn,

requiring very little time and energy to become

proficient in the control of the DTS-1600A.

The GUI provides control over the following pa-

rameters:

• Output Voltage from 0 to ±1600V

• Pulse Width from 1µs to 4.75ms

• Pulse Frequency from 200Hz to 20KHz

• Oven temperature from ambient to 180°C

• Enable/disable testing of each sample

• Pulse rate-of-rise time for each sample

• Current trip setpoint for each sample

• File logging of all test data

Test data are logged in a standard ASCII text file.

From this file, the user can retrieve data corre-

sponding to the start of each sample test, failures

of individual samples, as well as periodic test pa-

rameter updates. The log file can be imported into

and analyzed using a spreadsheet program such

as Microsoft Excel or Lotus 1-2-3.

The main GUI control screen is shown in Figure 4

above.

The DTS-1600A is a fully integrated test system,

ready for use. The control software is designed to

enable immediate use of the system, without ad-

ditional programming on the part of the user.

SYSTEM OVERVIEW

The DTS-1600A system consists of three basic

modules. The first module is the Pentium proces-

sor-based control computer and General Purpose

Interface Bus (GPIB). The computer and GUI op-

erate as the master control unit, and allow the

user to interface with the system. Using software

created in the National Instruments LabWindows/

CVI environment with custom defined functions,

the user has complete control of the system from

this location. The control computer interfaces to

the slave control unit over a GPIB bus.

The rack-mounted slave control unit and high

voltage section is the second module. It consists

of a GPIB interface, a microcontroller and pulse

generator, five ±1600V pulser modules, oven

control circuitry, front panel interface, and high

voltage and support power supplies. The internal

microcontroller is responsible for decoding the

software commands from the control computer

and implementing them in hardware. It communi-

cates with all peripheral cards via an internal RS-

485 interface.
