1. Instroduction

This is one of the second-generation USB DSO (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 USB DSO 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.

Real Time Sampling Frequency (fs)		Single Analog Channel 100 MHz Single or Dual Analog Channels 50 MHz, 40 MHz, 20 MHz, 10 MHz, 5 MHz, 4 MHz, 2 MHz, 1 MHz, 500 kHz, 400 kHz, 200 kHz, 100 kHz, 50 kHz, 40 kHz, 20 kHz, 10 kHz, 5 kHz, 4 kHz, 2 kHz, 1 kHz, 500 Hz, 400 Hz, 200 Hz, 100 Hz, 50 Hz, 40 Hz, 20 Hz, 10 Hz, 5 Hz, 4 Hz, 2 Hz, 1 Hz
Equivalent Sampling Frequency		= [Real Time Sampling Frequency] × [Number of Frames Persisted]. Maximum 20 GHz, for repetitive signals whose maximum frequency is less than ¼ of the real time sampling frequency. Not valid for the case of post-trigger.

	Record Mode (Streaming Mode)	Limited only by hard disk space available and maximum file size allowed by the operating system. Maximum sampling frequency for continuous streaming is computer speed and software setting dependent and typically 10 MHz (single channel, 8 bit) in Multi-Instrument.
