Abstract: This paper introduces the postulate of virtual instrument, proposes a new uncertainty evaluation method for virtual instrument measuring voltage, firstly evaluates uncertainty for hardware of virtual instrument, and the programme which giving the emulational signal accord with the capability of hardware, deals with the emulational signal accord to measure algorithm of virtual instrument〖KG-*3〗, and acquires the result of uncertainty evaluation by making statistical analysis. This method is the same with other measuring of virtual instrument.

Key words: virtual instruments, data acquisition, uncertainty evaluation
