Virtins Sound Card Spectrum Analyzer V3.1

Virtins Sound Card Spectrum Analyzer 3.1 Description

" Virtins Sound Card Spectrum Analyzer : Sound card based real time oscilloscope and spectrum analyzer with sophisticated triggering method including pre-trigger and post-trigger which are generally missing from other sound card based instruments. It is a part of VIRTINS Multi-Instrument. . "

Editor: Virtins Sound Card Spectrum Analyzer - VIRTINS Sound Card Spectrum Analyzer is a powerful PC based virtual instrument. It consists of a sound card real time oscilloscope and a sound card real time spectrum analyzer and can run them concurrently. 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 Spectrum Analyzer 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. 1. The dual-channel Oscilloscope, with all of the features of a modern digital storage oscilloscope, provides 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. 2. The dual-channel Spectrum Analyzer provides four types of views: ( 1 ) Real time Amplitude Spectrum display. ( 2 ) Real time Phase Spectrum display. ( 3 ) Real time Auto Correlation display. ( 4 ) Real time Cross Correlation display. with adjustable FFT points ranging from 128 to 32768 and selectable windowing functions such as Rectangle, Triangle, Hanning, Hamming, Blackman. It is a part of VIRTINS Multi-Instrument.
