CADDA 计算机控制的A/D和D/A转换器单元（PC）

The Computer Controlled A/D and D/A Converters Unit, "CADDA", unit has been designed to help the students to learn how to perform the most common procedures and study the different circuits used to convert analog signals in a digital signals and vice versa.

The unit also allows the user to study in detail other circuits related with the analog to digital conversion and digital to analog conversion, such as adder circuit, sample and hold circuit, series converter, frequency to voltage converter, etc.

The unit includes a data acquisition system to acquire multiple analog signals and show the signals on the computer. The data acquisition system allows the user to generate a variety of waveforms (with the analog outputs) in order to test the different circuits with different analog signals. The data acquisition system also allows to use 24 digital inputs/outputs configurable as inputs or outputs.

The "CADDA" unit includes the following elements:

• N-M60. Analog/Digital Converters Module.
• N-M61. Digital/Analog Converters Module.
• EDAS/VIS-0.25. EDIBON Data Acquisition System and Virtual Instrumentation (speed: 250,000 samples/s).

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.
