The BRAT^® Option B504 HIGH SPEED DIGITAL TEST SYSTEM

Seven Distinct I/O Memory Types

Each Module contains seven separate memory banks, each 64K vectors in depth, for generating stimulus patterns, expected response patterns, and recording UUT response data. All memory banks operate at full 50 MHz data rates.

The Stimulus Memories consist of the Output, Tristate, and Algorithmic Output memories. The Output Memory contains the actual data patterns to be generated to the UUT. Tristate Memory provides tristate control which supports bidirectional I/O. The Algorithmic Output Memory determines which algorithmic pattern will be output.

The Response Memories consist of the Expect, Mask, and Algorithmic Expect memories. The Expect Memory contains the expected response data for the UUT and is the basis for input compare operations. The Mask Memory determines which patterns are to be ignored for input response comparison. Algorithmic Expect Memory determines which algorithmic expect pattern will be compared against the UUT input response.

Record Memory is used to store either the UUT response data or the result of the comparison between the UUT response data and the expected response pattern.

Data Formatting with Precise Edge Placement

Stimulus pins may be independently programmed for any of the following data formats: Non-Return to Zero (NRZ), Return to Zero (RZ), Return to One (R1), Return to Complement (RC), and Return to Inhibit/Tristate (RI).

Each Module contains 16 timing generators for stimulus edge placement and pulse width timing. Output pins can select from 2 pairs of timing generators to define the leading and trailing edges of each signal pin. Groups of eight output pins share an independent set of 2 timing generator pairs for a total of 8 stimulus timing generator sets per card. 100 ps edge placement resolution provides precise UUT timing for bus emulation testing, memory testing, and functional testing.

Response pins can select from 2 response timing generators to define the sample and compare edges, or the 2 response timing generators can be combined together for window compare with glitch detection.

B504

The BRAT^® Option B504 is a 50 MHz digital test system utilizing Commercial-Off-The-Shelf (COTS) equipment in a modular design. The reconfigurable assembly allows easy access to all of the modules as well as room for expansion/reconfiguring. The interface provides from 320 to 640 high speed digital input/output pins, analog test points, and AC and DC Power.

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 I/O pins operate at up to a full 50 MHz data rate. The system offers 64K Vectors per Channel, RAM-Backed and Algorithmic Pattern Generation, NRZ, RZ, RONE, RTC, and RI Output Data Formats, and 16 Stimulus Timing Generators per Module.

Multiple Programmable AC and DC

The power system is a reconfigurable precision power subsystem designed to meet the challenges of high tech ATE.

High Channel Density

Each Module provides 32 stimulus pins and 32 response pins in a single C-size slot. Up to 20 I/O modules may be controlled by a single Control Module. Input and output pins are grouped on separate
