The first half of this video discusses the uses of a small piece of free software you can download called a dual function generator it creates tones using your soundcard, from 2 hz to 20,000hz. That won't affect your using the function generator, but it will prevent you from using the built-in auto-calibration system to calibrate the sound card attenuators. Directly from the sound card (with a microphone or line input), or from a source such as a cd or mediaplayer the input to the oscilloscope is defined by the windows soundmixer (see below. When used in conjunction with multi-instrument software, these vt dsos convert any desktop, laptop, or tablet pc into a powerful oscilloscope, spectrum analyzer, multimeter, data logger, signal generator and so forth, all of which work simultaneously.
Another device on your computer already does this: the sound card the main differences are the level of voltage each can handle, and how fast they sample the voltage (more on that later) since the sound card on your computer can only handle a small amount of voltage (around +/- 6v to 8v) you need to scale it down. A pc with sound card serve as an audio waveform generator, a two-channel digital oscilloscope and a spectrum analyzer in effect, a desktop computer with a full-duplex sound card can function. Virtins sound card oscilloscope is a powerful pc based virtual instrument software unlike most of the sound card oscilloscopes in the market which search trigger of data is collected.
The sound card is ac coupled and has a very limited bandwidth i wrote a program to use the sound card as the input for the roller sensor on a homemade motorcycle dyno when i tried using a similar setup for the dynamic balance program it would not work because the frequency of the vibration sensor fell below the minimum bandwidth. 5 the pc-based soundcard oscilloscope receives its data from the sound card with 441-khz sampling rate and 16-bit resolution also available is waveio, a soundcard interface for labview software also available is waveio, a soundcard interface for labview software. The pc based soundcard oscilloscope receives its data from the soundcard with 441khz 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.

Pc sound card as a function generator and oscilloscope sound card sound card present in personal computers facilitates the input and output of audio signals, under the control of a driving software eg in multimedia. Oscilloscope _ an oscilloscope (also known as a scope, cro, dso or, an o-scope) is a type of electronic test instrument that allows observation of constantly varying signal voltages, usually as a two-dimensional graph of one or more electrical potential differences using the vertical or 'y' axis, plotted as a function of time, (horizontal or 'x' axis. Can measure frequencies up to about 15 khz which might not be possible with a single-supply rail device22 it offers all the desired functions listed in table 1 and an oscilloscope package that employs the sound card of a pc. Sound card sound card present in personal computers facilitates the input and output of audio signals, under the control of a driving software eg in multimedia this device can be used as an oscilloscope for signals up to a frequency of 20 khz.
Find great deals on ebay for pc oscilloscope card shop with confidence. Once i need an oscilloscope to see the electrical voltage ripple in the car ignition systems, alternator rotation, high-beam lights flicker, and others are generally emit noise or voltage ripples, well, this is what i want to know, size of the noises, etc oscilloscopes are very expensive tools, and generally are only used in electronics / electrical laboratory. The availability of inexpensive pc sound cards that can simultaneously play and record stereo digital audio files permits a single pc to function as both a signal generator and as a dual-channel. Sound card present in personal computers facilitates the input and output of audio signals, under the control of a driving software eg in multimedia this device can be used as an oscilloscope for.
Directly from the sound card (with a microphone or line input), or from a source such as a cd or mediaplayer the input to the oscilloscope is defined by the windows sound mixer (see below. An oscilloscope photo shows a 1-khz triangle wave such as those generated by cheap sound cards the photo shows rounding of the points of the triangle wave due to limited high-frequency bandwidth the photo shows rounding of the points of the triangle wave due to limited high-frequency bandwidth. Basic oscilloscope, spectrum analyzer, multimeter and signal generator functional tests using multi-instrument and pocket multi-instrument with sound cards.
The pc sound card as a signal generator or oscillator: audio frequency signal generator - 100hz to 15 khz sine waves only digital signal generator - sine wave, square wave, trigon wave, beat wave, swept sine & white noise. This program includes oscilloscope, spectrum analyzer, sound generator and numerous knobs and buttons as well as sliding controls that mimics like a real test gear of your dream as the name implies, this program can measure frequencies up to the limit of your sound card, from few hz up to 15 khz. Test tone generator - this test tone generator (ttg) turns your pc into a function generator and enables you to demonstrate, test and tune sound systems, create sound effects and a whole range of other uses to suit your needs it can also be used for educational purposes.
Please give me as many resources and advices as you can see below i will display outputs on a computer screen use a sound card to capture waveforms - it won't work with dc signals but will work from 20 hz to 20 khz at normal sampling rates. I've connected the output of the signal generator to the input and i've connected channel 1 of the oscilloscope probe to the output and i've connected channel 2 of the oscilloscope to the input. The major benefit of this setup is that the sound card is isolated from the output that is going to the oscilloscope the speaker system's default amplifier is doing the isolation if you short circuit the signal wires, the worst that will happen is your crappy old speakers may get damaged, but your audio card is safe.
