Virtins Sound Card Spectrum Analyzer 2.1

Virtins Sound Card Spectrum Analyzer is a strong 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 who search trigger event after data collection, it options a specially designed data acquisition approach who 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 who are generally missing from other sound card based instruments. 1. The dual-channel Oscilloscope, with all of the options of a modern digital storage oscilloscope, provides four types of views: (1) Real time wave form display of Channel A and Channel B. (2) Real time wave form display of Channel A + Channel B. (3) Real time wave form display of Channel A - Channel B. (4) 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.
