VIRTINS Multi-Instrument

VIRTINS Multi-Instrument is a specialized virtual instrument for Windows PCs. It includes a sound card real-time oscilloscope and a spectrum analyzer that can be run concurrently.

It offers a specially designed data acquisition approach, making it possible to monitor the input signal continuously and avoid missing any trigger events before collecting the frame of data.

VIRTINS Multi-Instrument is designed to offer a screen refresh rate that typically rests around 50 frames per second, the intention being to provide a real-time response. As far as the triggering method is concerned, it is worth noting that pre-triggers and post-triggers are supported.

The dual-channel oscilloscope provides a total of four types of views; each presents the waveform data in a different fashion. For instance, it can display data from each channel separately or combine the information, as well as offers a real-time Lissajous pattern display for channel A and channel B.

Similarly, the dual-channel spectrum analyzer offers four different views: real-time phase spectrum display, real-time amplitude spectrum display, real-time autocorrelation display, and real-time cross-correlation display.

FFT points are adjustable in a range going from 128 to 32768, and users have access to selectable windowing functions, such as Triangle, Rectangle, Hanning, Hamming, and Blackman.
