What Is a Data Domain?

The measurement of the logical characteristics of digital systems is mainly used to detect, locate or diagnose faults in digital systems. Data domain measurement is a measurement technology developed in the late 1960s and early 1970s. The Data Domain function is used to define the characteristics to be applied to the data definition. When a field is added to a row definition, the field inherits the attributes of the data definition and its data fields. The data field specifies the data type, and applies the allowed minimum and maximum values and other constraints.

The sequence of binary coded pulses processed by a digital system is often called data. Integrated

In digital circuits, abnormal actions caused by defects in materials and processes are called

The main purpose of data domain measurement is to find the most complete and short test set possible, generate the test patterns required for the test, capture and display the output patterns, and complete the fault detection or location.

The instrument that generates the test pattern is called a pattern generator, or digital generator. An instrument that captures and displays output patterns in various ways is called a logic analyzer, or fault finder. There is also a class of simple instruments that use data compression technology for incomplete measurements, called feature analyzers.
