Measurement Methods and Diagnostic Techniques for the Digital Television Tape Recorder (DTTR)
The introduction of the digital television tape recorder (DTTR) will change all Test and measurement procedures dramatically. Today a service engineer can monitor the analog waveforms with a simple oscilloscope and decide which part of the system is faulty. This is not possible with the DTTR, because the video and audio signals are digital data streams which are processed in many ways. Engineers will therefore have to devise new ways to simplify the testing procedure to achieve better maintenance and serviceability of the system. This article describes some of the methods used for testing, and stresses the need for built-in diagnostics.
