Testing a data link can be a complex activity.  GDP provides equipment to generate test data streams, detect errors in the return link and manipulate the data stream to produce intentional errors to simulate unique conditions.  Our Bit-Error-Rate-Testers (BERTs) generate standard maximal length pseudo-random data or fixed patterns for testing data links or bit detection (bit synchronizers) equipment.

SGLS / Ternary-Signal data-link testing is a unique capability available from GDP.  All three signal states are exercised and decoded by our unique differential encoder / decoder.
