Virtins Sound Card Oscilloscope 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.
Specification

Scan 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

Four view types: Real time waveform display of Channel A and Channel B, Real time waveform display of Channel A + Channel B, Real time waveform display of Channel A - Channel B, Real time Lissajous Pattern display for Channel A and Channel B

Independent X axis and Y axis zooming and scrolling

WAV file can be imported for display and analysis

Collected measurement data can be saved as WAV file or exported as TXT file

Data curve can be printed out directly or saved as BMP file

Support calibration of the input channels for different gain settings

Support adding notes to the measurement data

Fast display refresh rate: about 50 frames per second (tested under Windows XP SP2 on IBM ThinkPad R51 Laptop PC with Intel (R) Pentium (R) M processor 1.60 GHz, with scan time=10 ms and FFT size=1024 and both Oscilloscope and Spectrum Analyzer running under "no trigger" mode). Thus data are displayed and analyzed in "true" real time

The colors of display are configurable

Number of points to be collected per scan can be fine tuned at one point's resolution

Display the Maximum, Minimum, Mean, RMS values of the data per scan. Therefore it can be used as a voltmeter

Support one cursor reader and two markers which stick to the measurement data

Five chart types: Line, Scatter, Column, Bar, and Step

Support combining data from individual channels of different wave files and extracting data from a wave file

Support normal and inverted display of waveform

Support Multilingual User Interface under Windows 2000, XP, 2003 and above. Currently supported languages are English, French, German, Italian, Portuguese, Spanish, Simplified Chinese, Traditional Chinese, Japanese and Korean. Support only the local language and English under Window 95, 98, Me and Windows NT
