Teleprinter and digital data signal decoder/analyser - this page is a stub


W-4100, later also W-4100D, is a standalone teleprinter and data signal decoder/analyser, introduced in 1993 by WAVECOM Elektronik AG in Bülach (Switzerland), as the successor to the W-4010. It is capable of decoding and displaying textual data sent by means of more than 100 com­munication modes. The W-4100D model 1 was introduced in 1996. The device can be re­garded as a competitor to the GA-082 FSK Analyzer made by Rohde & Schwarz in Germany.

In 1996, the W-4100 was succeeded by the W-4100D, which had a Digital Signal Processor (DSP), hence the suffix 'D' to the model number. The W-4100D was succeeded in 1996 by the W-40, which was based on an ISA-bus interface card that could be placed in a regular PC of the era.
