Mark Roos is the founder and CEO of Roos Instruments, a position he has held since its inception in 1989. Mark graduated from California State Polytechnic University with a B.S. in Electrical Engineering in 1973 and holds a MS in Electrical Engineering from Stanford University and an MBA from Santa Clara University. Measurement technology has been the focus of his entire career starting with his early work experience as R&D Project Leader for Hewlett-Packard (later Agilent) Network Measurements Division in Santa Rosa where he was responsible for the microwave receiver and processing (i.e. "bottom box") of the record-breaking HP 8510 Microwave Network Analyzer. After the enormous success of that network analyzer, Mark went on to lead the marketing efforts for HP's RF and Scalar Microwave Network Analyzer products. The next phase of Mark's career was VP of Engineering for EIP Microwave, a maker of electronic counters and other instrumentation. While at EIP, he discovered a need for high performance automated instruments. He left EIP to found Roos Instruments to serve this market for high-speed RF instrumentation with capabilities suitable for high volume manufacturing. Early on, Roos Instruments received funding from DARPA via a Small Business Innovative Research (SBIR) grant. The grant allowed Roos Instruments to develop a totally new approach to RF measurements using a single receiver and advanced software -- ideas Mark pioneered. Early in 1994, Roos Instruments won a comprehensive benchmark at Motorola with the RI7100A, resulting in its first major success. Continuing innovate, Roos Instruments introduced Cassini, the first truly modular, high performance ATE. Thus continued Roos Instruments' rise as the supplier of these advanced technologies in production testers world-wide.
