Abstract
The analog test requirements of ISDN (integrated services digital network) U interface transceivers that use linear echo cancellation are investigated. These requirements exceed the performance of existing analog waveform instrumentation. A new high-performance analog waveform synthesizer and digitizer was evaluated for this application. Experimental echo cancellation results are reported
