Testing of high-resolution / middle-speed A/D converters and modules problems and ways of their solving

We describe solutions, how to improve a quality of basic testing methods to be possible to use them for dynamic testing high-resolution/middle speed AD converters and AD modules. The following methods are described: an application of low-distortion band pass filters, a digital correction of a known distortion of a testing signal, an application of a two-tone (or multitone) signal, an application of a nondeterministic signal (noise). The method, which combines a filtration of testing signal and a following digital correction, is described and proposed as the perspective one. The AD transfer standard, which is applied for an evaluation of testing methods and systems is also mentioned
