Abstract
A measuring device or test device is provided which includes several functional units that are interconnected. The functional units are interchangeable or can be added or omitted in a variable manner. The measuring or test device can be configured with functional units whose functional characteristics differ in terms of precision and/or quality and/or functional scope.
Claims17
A device for measuring or testing, said device comprising:
- a plurality of functional units interconnected with one another to form a measuring or testing circuit,
- wherein at least two functional units of the plurality of functional units each have functional properties that provide for a different accuracy or a different quality as compared to the corresponding accuracy or the corresponding quality of the functional properties of the other of the at least two functional units,
- wherein the device is a spectrum analyzer, a network channel analyzer, or a signal generator,
- wherein the plurality of functional units are removable from said measuring or testing circuit in order to configure said measuring or testing circuit, and
- wherein the device is configured for a research and development application, such that the functional properties of at least one of the at least two functional units are characterized by a high dynamic response, high accuracy, and relatively slow measuring rate.
