DC2159A - FMC to USB Adapter to Interface with PScope



The PScope System is a USB-based product demonstration and data acquisition system for use with Linear Technology’s high performance ADCs and signal chain receiver family. PScope allows users to evaluate the SNR, SFDR, THD, as well as other key parameters, quickly and easily.  Use PScope software with the DC718, DC890 and DC1371 Data Collection Boards.

LinearLabTools is a collection of Matlab and Python programs that provide direct access to Linear Technology’s data converter evaluation boards.  An evaluation board for a data converter will typically plug into an accompanying controller board, which is then connected to a host computer running a Linear supplied GUI program such as PScope for Analog-to-Digital converters or LTDACgen for Digital-to-Analog converters. The GUI allows basic performance measurements to be made, but it is not designed to run arbitrary sequences of tests or communicate with other hardware, as is often required by customers when evaluating a part for their own application. LinearLabTools allows customers to control Linear’s data converter demo boards as they would any other piece of test equipment, using their own software.

The LinearLabTools package also contains various application examples, simulations, and educational programs that demonstrate mixed signal concepts.
