How to design the generator is introduced in detail. The Virtual Function Signal Generator can generate basic wave such as Sine wave, formula wave, white noise etc. The generator has functions like wave showing and date saving in addition. Keywords- Virtual Instrument; Labview;Function Signal Generator I. INTRODUCTION The function signal generator is applied in great many of fields. Virtual Instrument is a new type of instrument which has especial functions that old one do not have. One VI includes PC, hardware which is particularly designed and special software. Being a graphical programming language Labview is used for date gathering, instrument controlling and date analyzing. How to design virtual function signal generator by Labview is explained in detail in the following paper. II. TOTAL DESIGN According to the principle of function signal generator,four parts were designed to compose virtual function signal generator. These four parts are property setting, signal generating, wave showing and date saving. A. Panel of Generator In this system the panel are divided to property setting panelfig.1 and total structure panelfig.2Main options in the first one are frequency, amplitude, duty cycle and samples etc. about signal. These properties can be set in this panel. Total structure panel just includes four parts that were presented above and some additional parts.
