Virtins Sound Card Spectrum Analyzer 3

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 anteriorly the frame of data is collected.

As a result, it boasts a very fast screen refresh rate (typically 50 frame per second) and thus a truly real time response. It sustains sophisticated triggering method including pre-trigger and post-trigger which are generally missing from other sound card based instruments.

1. The dual-route Oscilloscope, with all of the features of a modern digital storage oscilloscope, provides four types of views: (1) Real time waveform display of route A and route B.
(2) Real time waveform display of route A + route B.
(3) Real time waveform display of route A - route B.
(4) Real time Lissajous Pattern display for route A and route B. 2. The dual-route 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 objectives such as Rectangle, Triangle, Hanning, Hamming, Blackman. It is a part of VIRTINS Multi-Instrument.
