Description

QuickEval-II software along with demonstration circuit DC718 provides a USB based Windows PC hosted digital data acquisition system supporting CMOS/LVTTL output ADCs up to 105Msps. The DC718 can be powered from either the USB port or from an external 6-9VDC Power supply (for lower noise operation or very high speed operation where the SRAM power requirements exceed the USB port capability). The Linear Technology supplied QuickEval-II evaluation software automatically detects the DC718 and in select cases can also detect the ADC demonstration circuit under evaluation. The QuickEval-II system provides for fast and easy performance evaluation of high speed ADCs by collecting up to 128K word samples and then performing various analyses on the data including calculating SNR, SINAD, THD, SFDR, ENOB and displaying the digitized input, an FFT of the data, the Primitive Wave of the sample set or a IFFT of modified frequency domain data to facilitate analyzing distortion products and sources. Figure 1 shows a block diagram of the DC718. The DC718 is connected to the ADC demonstration circuit via a 40 pin edge connector, to the PC by a USB A-B cable and to an optional power supply by a 5mm plug.

The QuickEval-II System is a USB-based product demonstration and data acquisition system for use with Linear Technology’s high performance ADC's. The system consists of a USB Data Acquisition Controller board that connects to individual daughter cards for specific Linear Technology ADCs. The software collects and analyzes data from the ADC in both the time and frequency domains and displays relevant parameters for the device being evaluated. The software also provides an automatic update feature to keep the software current with the latest set of device drivers.
