Virtins Sound Card Oscilloscope

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 event after data collection, it features a specially designed data acquisition approach which is able to monitor the input signal continuously without missing any trigger event before the frame of data is collected. As a result, VIRTINS Sound Card Oscilloscope boasts a very fast screen refresh rate (typically 50 frame per second) and thus a truly real time response. It supports sophisticated triggering method including pre-trigger and post-trigger which are generally missing from other sound card based instruments. VIRTINS Sound Card Oscilloscope, with all of the features of a modern digital storage oscilloscope, providing four types of views: (1) Real time waveform display of Channel A and Channel B. (2) Real time waveform display of Channel A + Channel B. (3) Real time waveform display of Channel A - Channel B. (4) Real time waveform display of Channel A x Channel B (5) Real time Lissajous Pattern display for Channel A and Channel B. Various digital filters are supported. It is a part of VIRTINS Multi-Instrument.

Virtins Sound Card Signal Generator

VIRTINS Sound Card Signal Generator is a powerful PC based virtual instrument. It consists of a sound card based Signal Generator and an off-line Oscilloscope. 1. The dual channel Signal Generator (Sweep/Arbitrary/Function/Burst Generator) provides the following types of waveforms for output: (1) Sine (2) Square (3) Triangle (4) Saw Tooth (5) White Noise (6) Pink Noise (7) Multi-tones (8) Arbitrary via user-configurable waveform library (9) MLS (10) Musical Scale (11) DMTF, at either a fixed frequency, or a frequency that sweeps linearly or logarithmically within specified frequency range and time duration. Amplitude sweep is supported. 2. The dual-channel off-line Oscilloscope provides four types of views: (1) Waveform display of Channel A and Channel B (2) Waveform display of Channel A + Channel B (3) Waveform display of Channel A - Channel B (4) Lissajous Pattern display for Channel A and Channel B The off-line Oscilloscope can be used to view the signal generated by the Signal Generator. It can also be used to view the WAV files recorded by other sound recording software. It is a part of VIRTINS Multi-Instrument.

Multi-Instrument Lite

Multi-Instrument is a powerful multi-function virtual instrument software. It supports a variety of hardware ranging from sound cards to proprietary ADC & DAC hardware such as NI DAQmx cards. Functions includes: (1) Oscilloscope: Dual-trace waveform, Waveform addition, subtraction & multiplication, Lissajous Pattern, signal recording,digital filtering. (2) Spectrum Analyzer: Amplitude spectrum, octave analysis(1/1,1/3,1/6,1/12,1/24,1/48,1/96), frequency compensation, frequency weighting (A,B,C,ITU-R 468), peak hold, linear/exponential average, measurement of THD, THD+N, SNR, SINAD, Noise Level, IMD, Bandwidth, Crosstalk, peaks, harmonics, phase spectrum, auto/cross correlation, coherence function, transfer function, impulse response. Support 55 window functions & window overlap. (3) Signal Generator: Function/Multitone/Arbitrary waveform/Burst tone/MLS/DTMF/Musical scale/White noise/Pink noise generation, frequency/amplitude sweep, fade in/out. (4) Multimeter: voltmeter, sound pressure level meter(dB, dBA, dBB, dBC), frequency counter, RPM meter, counter, duty cycle meter, F/V converter, cycle mean/RMS, vibrometer. (5) Spectrum 3D Plot: waterfall and spectrogram. (6) Data Logger: long time data logging function for 129 derived variables, including RMS value, etc. Up to eight data logger windows can be opened and each window can trace up to 8 variables. (7) LCR meter: It is used to measure the value of an inductor, a capacitor or a resistor, or the impedance of a network of them. (8) Device Test Plan: It provides a mechanism for you to configure and conduct your own device test steps. It takes the advantage of the sound card?s (or other ADC/DAC device's) capability of simultaneous input & output, to generate a stimulus to the Device Under Test (DUT) and acquire the response from that device at the same time. Different stimuli can be generated and the response can be analyzed in different ways. Visit www.virtins.com for further details.
