<http://> Fastbit Technologies Quarterly Newsletter
Vol. 1 Issue1
August 2000 A quarterly newsletter for people in the communications
industry.
Fastbit Technologies is a company that values and commits itself to
engineering that simplifies broadband physical layer testing. We aim to
provide you with complete test instruments with unique features. The
founders of Fastbit originated from Tektronix, Hewlett Packard and Hughes
Aircraft. Collectively, they have more than sixty years experience in
transmission test equipment development, with world-class expertise in
high-speed digital design, DSP, analog, RF, and software development. Our
products are developed by test engineers for test engineers. Fastbit's
product list includes: The FB100A - a high speed bit error rate test system,
the FB2000A - a frequency tunable carrier/noise test system, and the FB3000A
- a QPSK/QAM cable modulator.

article1BERT ASI Interfacing directly to the DUT via Pod
A unique feature of the FB100A is it's interface capabilities, which offers
a selection of parallel interface pods that provide a wide variety of test
interface configurations. One of the interfaces supported is ASI.
The FB100A ASI Generator pod converts the FB100A's Generator parallel output
to a DVB-ASI compliant interface. The FB100A will automatically...
The FB100A ASI Analyzer pod converts a DVB-ASI compliant interface to a
suitable parallel interface for the FB100A Analyzer for error analysis...
