Virtins Sound Card Spectrum Analyzer
-
Version
1.0
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 Instrument boasts a very
fast screen refresh rate (typically 15 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 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
