Daqarta v3.50
Data AcQuisition And Real-Time Analysis
Scope - Spectrum - Spectrogram - Signal Generator
Software for Windows
Science with your Sound Card!

Daqarta uses your Windows sound card to provide high performance waveform and FFT spectrum analysis, color spectrograms, signal averaging, signal generation, and advanced options for lab or personal use. Daqarta allows easy calibration of all line sensitivities and volume controls, so you can read signal values directly in Volts or any other units you define.

New in version 3.50, Daqarta offers free-floating resizeable Voltmeter and Frequency Counter options, loaded with advanced features. The new Spectrum Cursor Peak option provides enhanced frequency and amplitude resolution, and the Track option automatically maintains the solid cursor over the largest spectral peak at all times.

Download Daqarta now and try it FREE for 30 sessions or 30 days.

You can purchase Daqarta for as little as US $29.00 ($99.00 Professional) to keep using all Daqarta features. Note that this includes a permanent license that will work with all future versions of Daqarta... you only pay once.

But, even if you don't buy, Daqarta will keep on working with only the signal inputs disabled. Essentially, it reverts to a freeware signal generator (previously offered separately as DaqGen), plus all the advanced Daqarta features like:

Multi-channel display shows all active channels simultaneously, on the same axes.

Dual cursors and readouts allow direct reading of waveform or spectrum values, as well as their difference or the summation of the values (area) between them for true RMS calculation.

Expandable X and Y axes allow magnification of selected portions of waveforms or spectra.

Advanced Trigger options allow you to see what happened before or after the trigger event.

256-color Spectrograms show time, frequency, and amplitude in a "voiceprint" format. Full control over color palette and dynamic range.

Data file operations allow you to save signals for later analysis, as single-screen or arbitrary length (DDisk) files. Even after the trial period, this allows you to to create your own Arb or Play Wave files for the Generator, for example.

You can open saved files, including standard WAV files collected elsewhere, to analyze waveform, spectrum, or spectrogram displays of file data. Even many "unsupported" formats can be opened via manual selection of format parameters.

Calibration values remain in effect even after the trial period.

Extensive Help includes tutorials on Fourier Transforms, synchronous waveform averaging, applications, and much more.
