Use Your Laptop As Oscilloscope: Oscilloscope is an electronic test instrument that allows projection of voltage signals to be displayed and learned. A specific circuit in the oscilloscope creates repeated moving signals from left to right. Download xoscope: digital oscilloscope for free. Xoscope is a digital oscilloscope using input from a sound card or EsounD and/or a ProbeScope/osziFOX and will soon support Bitscope hardware. Includes 8 signal displays, variable time scale, math, memory, measurements, and file save/load. Author: Christian Zeitnitz. Main features: The PC based Soundcard Oscilloscope receives its data from the Soundcard with 44.1kHz and 16 Bit resolution. The data source can be selected in the Windows mixer (Microphone, Line-In or Wave). The frequency range depends on the sound card, but 20-20000Hz should be possible with all modern cards.
