Vol. 1=20 = Issue1 = = = = = = = = = =20 August 2000 A quarterly newsletter for people in the = communications=20 industry.

Fastbit Technologies is a company that values and = commits=20 itself to engineering that simplifies broadband physical layer = testing. We=20 aim to provide you with complete test instruments with unique = features.=20 The founders of Fastbit originated from Tektronix, Hewlett = Packard and=20 Hughes Aircraft. Collectively, they have more than sixty years = experience=20 in transmission test equipment development, with world-class = expertise in=20 high-speed digital design, DSP, analog, RF, and software = development. Our=20 products are developed by test engineers for test engineers. = Fastbit's=20 product list includes: The FB100A - a high speed bit error rate = test=20 system, the FB2000A - a frequency tunable carrier/noise test = system, and=20 the FB3000A - a QPSK/QAM cable modulator.
