Sound Card Spectrum Analyzer Publisher's Description

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, 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.
