Program description

Virtins Sound Card Oscilloscope is a powerful PC based virtual instrument software. 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 Oscilloscope 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. Virtins Sound Card Oscilloscope, with all of the features of a modern digital storage oscilloscope, providing 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. SpecificationScan Time: 100 #s~500 s (depending on Computer Memory) Bandwidth: 10 Hz - 96 kHz (depending on Sound Card) Maximum Allowable Input Voltage (if connected directly): about 2 VAC (depending on Sound Card) Selectable sampling frequency (up to 192 kHz), sampling bit resolution (8, 16 or 24 bits) and sampling channels (one or two) (all depending on Sound Card) Four triggering modes: no trigger, repeated trigger, single trigger and slow trigger. Support triggering by leading edge or trailing edge at specified triggering level and on selected input channel Support pre-triggering and post triggering from 0 to 100% of the selected record length Continuously monitor the input signal such that no trigger event is missed before data collection. Can be used as a transient signal recorder to capture and store data for up to 500 s ...
