Virtins Technology, which publishes software that uses a PC sound card as the heart of several software instruments, has released a similar program for the Pocket PC.Virtins Pocket Instrument uses the sound card chip in your ppc to turn your windows mobile based handheld into an spectrum analyzer, a oscilloscope , or a signal generator.

Turn your Pocket PC handheld computer into oscilloscope

The spectrum analyzer lets you view amplitude spectrum and phase spectrum. The signal generator supports multitone generation where you can combine up to 32 tones in each channel. It also supports arbitrary waveform generation through a user-defined waveform library.

The oscilloscope has a selectable sampling frequency of up to 96 kHz, a sampling bit resolution of 8 or 16 bits, and one or two channels.All specs depend on the capabilities of the Pocket PC's sound device.

Virtins Sound Card Instrument features zooming and scrolling function and allocates most of the screen for data display, all of which are essential for you to explore the fine details of the measurement data. In contrast, most of other sound card based instrument spent much precious screen space to simply mimic the panel of the conventional instrument.

Virtins Sound Card Instrument provides a comprehensive range of functions including wave form addition, wave form subtraction, Lissajous Pattern display, Voltmeter, transient signal recording, RMS amplitude spectrum display, relative amplitude spectrum display, phase spectrum display, auto correlation coefficient display, cross correlation coefficient display, function generation, arbitrary waveform generation, white noise and pink noise generation and sweep signal generation, etc.

For Virtins Sound Card Oscilloscope and Virtins Sound Card Spectrum Analyzer, it is possible to specify a trigger event for collecting a frame of data. A negative or positive trigger delay can be specified so that collecting data can be started before or after the trigger event. Virtins Sound Card Instrument features a specially designed data acquisition approach which is able to monitor the input signal continuously without missing any trigger event, before a frame of data is collected into the PC memory after the trigger event is found. This makes Virtins Sound Card Instrument suitable for transient signal recording for up to 500 seconds as long as the memory allows.

It is the first sound chip based oscilloscope, spectrum analyzer, signal generator pocket PC software in the word, the pocket PC version of Virtins Sound Card Instrument.
