Winscope is a freeware application that will display the waveform of an input signal on your screen. It also allows you to display realtime signal spectra and plot Lissajous patterns. It uses your sound card to sample the input signal and requires no external hardware. All the controls are managed through a point and click PC software interface. The application will run on any Windows OS and can run alongside other programs. It is very easy to use and will allow you to get results quickly.
When you first run winscope it will present a multi document interface with a toolbar and a host of child windows. The Messages window provides a hierarchical list of all messages in the program, and you can choose to record all or a subset of these. The API window likewise displays a hierarchical list of all the API functions called, and you can record all or a subset. The remaining two windows allow you to display the window hierarchy and the device screen synchronized with the trace, and they can be navigated together with the timeline.
Another feature that makes winscope useful is the ability to display all channels in the graph window simultaneously. This is especially useful when multiple voltage or current sources are being monitored. In addition to this, it is possible to select a single channel in the Legend area by clicking on its name. This will enable a wider line for that channel and it is then possible to follow the change in its value over time.
