1. Apparatus for measuring timing characteristics of bursty message traffic over a low to moderate rate digital transport or transmission medium comprising:

  • means for generating a reference pulse stream;

    a transcoder device receiving said reference pulse stream and routing the pulse stream to a device or transmission medium under test and, in analog form, to a first channel input of a multichannel analog-to-digital capture an/or recording device, the transcoder further receiving an output pulse stream from the device or transmission medium under test and routing the output pulse stream, in analog form, to a second channel input of the analog-to-digital capture and/or recording device; and

    means for processing and analyzing captured pulse streams so as to measure one or more timing characteristics of the output pulse stream from the device or transmission medium under test.
