SyntheSys Research
SyntheSys Research was a Silicon Valley test equipment company that existed from 1989 to 2010, located in Menlo Park, California. The company was founded by Tom and Jim Waschura, with technical help from other ex-Ampex employees Rob Verity and Kirk Handley. The first product was a 160 Mbit/s bit error rate tester (BERT) called the BitAlyzer 160 that debuted in 1989. The company patented key technologies used in modern signal integrity test; notably ''Error Location Analysis'' and statistically deep eye-diagramming integrated with BERT measurement called ''BERTScope''. The company was the first to combine Jitter sources in its test signal generators to permit popular ''Stressed-Eye'' testing. The company developed many products over its 21-year span, including specialty products for disk-drive, television, high-definition television, optical, telecommunications, and computer applications. In 2010, SyntheSys Research was purchased by Tektronix (a subsidiary of Danaher Corporation) in an M&A transaction and the BERTScope and BitAlyzer instruments became product lines in Tektronix's high-speed Oscilloscope divisions.
== Founding ==
The company was founded by Tom and Jim Waschura, identical twins who formerly worked for Ampex Corporation in Redwood City, California. Tom Waschura's electrical engineering degree from M.I.T. landed him a job at Ampex's Data Systems division working on tape recording and early parallel-transfer disk drives. Jim Waschura's software engineering background proved useful in Ampex's Video Systems division, working on 'still stores' used for broadcast television, especially news production. Tom left Ampex and the brothers created a partnership called Designware Associates to assist a fledgling company called Systems West create the first polar-orbiting satellite image retrieval system for commercial boating and fishing. Later, Tom recalled a senior engineer at Ampex, John Corcoran, working to add digital communications channels to analog tape recorders that Ampex manufactured. John and Tom employed a device known as a Bit Error Rate tester (BERT) that generated a pseudo-random series of bits to record and later to be played-back into the BERT device that verified that the bits had been reproduced correctly. This effort was undertaken about the same time early personal computers were becoming available, known as "PC/AT" or 80286-based personal computers. Whereas the BERT device indicated the number of bits that were incorrectly reproduced, it became clear that the effort of implementing a digital communications channel on an analog tape recorder would be greatly helped if it were clear which bits were in error -- not just the quantity of the erred bits -- and it seemed the new ''powerful'' personal computers ought to be able to do this. This became the genesis of ''Error Location Analysis'' technology that was later patented and implemented in all ''BitAlyzer'' and ''BERTScope'' products, and that was licensed to Hewlett Packard Company (later called Agilent Technologies, and now called Keysight) who implemented it in their popular 86130 3.0 Gbit/s BERT instrument.
The first BitAlyzer was developed in the garage of a residence in the Emerald Hills area of Redwood City owned by Bob Haya. Rob Verity and Kirk Handley, each a former co-worker of Tom Waschura's, developed hardware modules, while Tom Waschura developed the system design and Jim Waschura developed the software. Bob Haya is credited with coming up with the name ''BitAlyzer.'' The company was incorporated as SyntheSys Research because DesignWare was not available for use. The first patent was filed on Error Location Analysis technology.〔https://www.google.com/patents/US6636994〕 The company moved to a small business park in Redwood City, California, where it resided for about a year before finally moving to Edison Technology Park in Menlo Park, California.
