The basic system consists of a 225 MHz pattern generator, 10 clock drivers, 6 DC
biases, 1-4 channels of 10 MHz 14 bit analog data acquisition and/or 1-4 channels of
digital acquisition. Additional options can be added to customize the system to
meet your requirements. The system software controls all of the internal
instrumentation and interfaces directly with external controllers and device
handlers providing an easy environment to create test programs and control test
procedures. Each analog data acquisition channel is complete with Global Offset
Correction, Gain, Filtering, A/D Converter and optional Correlated Double
The digital acquisition card can be
configured to handle one or two digital data streams up to 32 bits wide. The system can
be expanded with additional acquisition cards, clock drivers and bias supplies.
Reconfiguring the System 1828 for the next device to be tested requires a
minimal amount of time. Typically the reconfiguration consists of changing the
DUT interface card and selecting the appropriate test plan.
The system software, PI-DATS, was written for users of all Pulse Instruments Test Systems. This
software implements a programming structure that uses visual objects to
replace programming language. This graphical software environment
provides a simple method to rapidly generate device test plans. PI-DATS
uses a password security system that protects device test plans from
unauthorized modification. PI-DATS allows the test engineer to define
test conditions prior to test execution using a Test Plan Edit Screen.
The operator can enter or modify information in a Test Plan pertinent to
the device being tested.
An entire test sequence can be stored in a
single file including interfacing with a parts handler. PI-DATS software
has been in daily use for the test of CMOS, CCD and IR Imagers for over
four years. During this period there has been a full time effort to
expand the functionality, and to enhance the capabilities based upon
user feedback and changing industry requirements. The software runs
under Windows XP for a high level of compatibility with third party
hardware, systems, and software.
