Virtins DSO 2A10E Package

Description

1. Introduction The Virtins DSO 2A10E Package is one of the second-generation USB DSOs (USB oscilloscopes) designed and developed by Virtins Technology. This generation of USB DSOs features Virtins Technology’s unique hardware-based DSP algorithm which enhances the performance and functionality dramatically without adding extra hardware cost. When used in conjunction with Multi-Instrument^® software, the Virtins DSO 2A10E converts any desktop, laptop, or tablet PC into a powerful oscilloscope, spectrum analyzer, multimeter, data logger, signal generator and so forth, all of which work simultaneously.
2. Package Contents 1) Virtins DSO 2A10E unit with a hardware bundled Multi-Instrument Standard software license
   2) 2 × 60MHz Oscilloscope Probe P6060 with two switchable positions: × 1, × 10
   3) Signal Generator Test Lead (1 m)
   4) USB cable (1.5 m)
   5) CD (contains the copy-protected Multi-Instrument Software and VT DSO-2A10E driver)
   6) Individual voltage calibration data

*DDS mode consumes almost no computer CPU time while streaming mode consumes a lot. Maximum sampling frequency for continuous streaming is computer speed and software setting dependent and typically 10 MHz in Multi-Instrument. More advanced functions are provided via Multi-Instrument software under streaming mode. Please refer to Multi-Instrument software manual for details.
