ScopeDSP

Users who are working with analog-to-digital converters could require a software package that would enable them to measure the performance or generate signals. ScopeDSP is a utility that was created for achieving such tasks and it will help people measure the characteristics of such A/D converters, generate signals, apply Fast Fourier transformations and compute time and frequency data statistics.

The application’s interface provides a classical layout, with some of the most often used features provided as quick access buttons and detailed context menus in the top. The bottom view area will serve as the signal plot, where one will be able to visualize the generated signal and its characteristic waveform.

A minimalist graph will be provided each time one will input the preferred signal parameters and generate its resulting waveform. However, the color palette for the graph cannot be adjusted and this could be a minor downside for some users, especially for complex plots.

One will be able to customize all the parameters that characterize the nature of the generated signal: sampling frequency, transformation, decibel level or processing. Specific ranges can be established and users will also be able to remove DC or rectify the signal output.

Statistical data can be displayed for the resulted signal and people can access a dedicated Fourier Transformation menu that will allow them to customize the length and time-to-frequency division. Several predefined shapes for the generated waveform are available (sine, square, triangle, sawtooth), but the application doesn’t provide a thumbnail preview for each one.

This application addresses experienced users who require a way of generating signal with the purpose of analyzing the analog-to-digital converter performance. It will allow them to customize the parameters of the output signal (sampling frequency, transformation, decibel level, etc.) and visualize the waveform of the generated signal on a Cartesian plot. Statistical data can also be displayed for the resulted plots, but novice users are advised to perform a thorough documentation in order to be able to interpret the data.
