A transportable high stable reference AD device was designed and realised for a comparison of systems for testing a dynamic quality of ADCs or AD modules two years ago. In spite of the fact that several comparative measurements were successfully executed, some limitations and imperfections were found out. Therefore a new innovated version of the device was(More)
The article describes a new method of Analog-toDigital Converters testing that is suitable for testing of highresolution AD converters (e.g. Σ-∆ or dither-based) or on the contrary ultra high-speed AD converters. The method is based on the histogram test driven by stochastic signal with defined probability density function. By repeating of the test for(More)
The Step-Gauss stochastic test method has been developed to enable testing of precise AD converters that are difficult to test by standard methods using deterministic signal. A transportable high stable reference AD device was designed and realised for a comparison of systems for testing a dynamic quality of ADCs or AD modules using mainly those standard(More)
Stochastic methods for ADC (analogue-to-digital converter) tests have been developed to enable testing of precise AD converters that are difficult to test by standard methods using deterministic signal. A transportable high stable reference AD device was designed and realised for a comparison of systems for testing a dynamic quality of ADCs or AD modules(More)
This paper shows implementation of Data Acquisition System for Analog-to-Digital-Converters ADC and Digital-to-Analog-Converters DAC in LabView. This system was developed for purpose of evaluation of ADC's and DAC's dynamic parameters using single and multi-frequency signal. Virtual Instrument was created in LabView to control data generation and(More)
