Millennium Modem/Channelizer Special Test Equipment

Abstract

A broadband modem/channelizer test set developed by NASA Lewis Research Center is discussed. The test set is a fully programmable, bit-error-rate (BER) test set designed for broadband modem-only and multichannel demultiplexer/demodulator characterization. It is currently configured for testing a multichannel demultiplexer/demodulator and was developed for the Advanced Research and Projects Agency under a Technology Reinvestment Program Cooperative Agreement entitled 'Millennium: 21st Century Broadband Digital Telecommunications Technology.' The test set can easily be modified to provide testing of other modems and multichannel demultiplexer/demodulator systems and is available to industry for such testing.
