DC2290A-B are evaluation boards used for especially Analog to Digital Conversion (ADC). For efficient analog to digital conversion, the use of ADC test boards is very important in finding optimal values for various parameters. DC2290A-B boards are specifically designed for testing the parameters in ADCs for an accurate data conversion.

The DC2290A-B kit includes all the components needed for the testing purpose. It has a designer analog interface board (DIB), which performs the actual conversion from analog to digital. The DIB also includes necessary instrumentation like a gain selector, a common-mode selector and an adjustable precision resistor for setting the input gain and common mode. It also contains a precision S-parameter analyzer (SPAR) for measuring the performance of the ADC under test. In addition the DC2290A-B kit has a data acquisition (DAQ) board for collecting and transmitting the data acquired during the ADC tests.

The DC2290A-B comes with four modules: the DIB, SPAR, DAQ and a programmable power supply. The programmable power supply is used to provide regulated power to the ADC under test and is configurable to ensure the best performance from the ADC under different operating conditions.

The DIB module consists of several components like a DC power supply, an instruction register, and two buffers that are used to send the control signals to the digital circuitry of the device under test. The data acquisition (DAQ) module consists of multiple channels that are used to collect data from the device under test. In addition, the DAQ board also includes a connector port which is used to connect external test equipment to the device under test. The SPAR unit consists of several components which are used to measure the performance of the ADC under test.

The DC2290A-B utilizes an FPGA (Field Programmable Gate Array) to program the instruction register, the gain selector and the common-mode selector. The FPGA allows for adjustment of the gain and common mode levels of the ADC under test. The DC2290A-B also provides a calibration system which is used to calibrate the ADC under test. This calibration system is used to set the optimal values for the parameters of the ADC.

The DC2290A-B also includes other features such as an oscilloscope, a frequency analyzer and a logic analyzer. The oscilloscope and frequency analyzer are used to determine the transfer function of the ADC under test. The logic analyzer is used to analyze the digital circuitry associated with the ADC.

The DC2290A-B kit is extremely versatile and can be used for testing various ADC parameters such as signal bandwidth, linearity, noise level, and dynamic range. The programmable power supply included in the DC2290A-B kit makes it a very useful tool for testing ADCs. The DC2290A-B is designed to provide accurate test results in the shortest period of time possible.
