The Software Design Of1.1GHz Synthesized Signal Source

The synthesized signal source is one of the most commonly used instruments in thefiled of electrical measurement.The synthesized signal source has functions of singlefrequency, sweep and modulation. It can generate sine wave signal which has adjustablefrequency and power. With the rapid development of Internet, the concept of remotecontrol gradually penetrates into the field of test and measurement. This trend brings anew operation and control to instruments. It is possible that testers can not visit the sitepersonally with the remote control system of synthesized signal source. To some extent,this manner can break the limitation of the use of traditional instruments in space.This paper describes the process of the software development based on theWindows CE system and proposes the software design of the synthetic signal source.This paper completes the design of local control software, remote control software andthe instrument driver. At the end of the paper, it proposes some problems encountered inthe process of debugging.The main content is as follows.(1) Local control software. According to the design requirements，this papercompletes the design of man-machine interface, the setting of instrument parameter andthe processing of the keyboard message.It also establishes a local server andcommunicates with the remote client.(2) Remote control software. According to the request, we need to design webpageof remote control, establish remote communication and send remote command.(3) The Instrument Driver. In this paper, we use the concept of dynamic link libraryand design instrument driver functions that meet the IVI specifition.At present, the synthesized signal software and hardware have finished the jointcommissioning.The various functions of the software have achieved the desiredobjectives.
