Spectrometer Transplant Embedded Operating System And The Design Of The Communication Module

As an instrument which measures the frequency domain of the signal, spectrum analyzer is widely used in electronic equipment testing, radar navigation, radio, mobile communications and many other fields. Intelligence, networking, high processing capability is an important direction of modern spectrum analyzer.The dissertation gives a method of embedded spectrum analyzer operating system transplantation and communication module design which in view of the characteristics that developping testing instrument with embedded system.Including hardware resources on the embedded system platform of spectrum analyzer, transplantation of BootLoader, customization of the WinCE operating system are discussed in detail, as well as USB virtual serial port and LAN port driver transplantation. The SCPI remote control communication between PC and spectrum analyzer through USB virtual serial port andFirstly, we introduce the interface resources of the embedded system platforms according to the demand of the spectrum analyzer and then complete transplantation of BootLoader, customization of the WinCE operating system, change the boot LOGO and hide desktop icon. In addition, we realize the transplantation such as USB virtual serial ports, DM9000A.Finally we establish a stable operating system platform for embedded spectrum analyzer.Secondly we design the SCPI remote communication module of embedded spectrum analyzer. SCPI remote control commands were sent based on the USB virtual serial port and LAN port.And finally we realize the remote control between PC and embedded spectrum analyzer.In the end, the dissertation gives a result of test, verifies the stability of the system platform and realizes the SCPI remote communication.
