The BRAT Test System
The Benchtop Reconfigurable Automatic Tester (BRAT) is an economical Commercial-Off-The-Shelf (COTS), flexible test system, based on an open architecture of commercial equipment in a modular design. Its primary use is as Automatic Test Equipment (ATE), either through test programming languages or by the use of the latest object-oriented graphical programming environments. The physical Benchtop Reconfigurable assembly allows easy access to all of the modules as well as room for expansion/reconfiguring, and makes transporting simple. The interface provides over 400 universal analog test points, 192 dynamic digital test points, 32 static digital test points, and 20 two-wire, 50 Ohm dedicated RF paths, reducing the number and complexity of ITAs.

State-of-the-Art-Technology
The BRAT features VXI instrument-on-a-card and modular technologies to provide complex testing capabilities in a compact workstation.

High Speed Dynamic Digital
The timing control lines operate at up to 160 MHz while the I/O pins operate at up to 20 MHz. 64K of memory are behind each pin, which can be run continuously or in segments for multiple tests.

Multiple Programmable DC and AC Power Supplies
The power system is a reconfigurable precision power subsystem designed to meet the challenges of high tech ATE.

Operating Environment
The standard operating environment is Windows(tm). The software packages installed are determined by the user's test requirements.

Multiple Instrument Synchronization
Complete access at the interface of all instrument "trigger" signals allows multiple instrument synchronizations, or "event" testing. This technique can reduce the software overhead for a test and increase throughput.

Measurement Capability to 250 MHz
Dedicated RF channels are used to route signals of up to 3 GHz to the analog bus; however, instrument measurement capability in the standard configuration is to 250 MHz.
