1. Demo Guide for a RF Editor COM 920 RF EDIT DEMO A Bir hnologies Company Introduction RF Editor is a drag and drop graphical spectrum editing tool that allows easy modification of I amp Q signals of any length It also provides the ability to combine spectrum files in the time and frequency domains to create custom spectrum specifically suited to an application This demo guide present exercises that illustrate numerous RF Editor functions in a self guided format To take best advantage of this guide readers should familiarize themselves with the operation of Spectro X a spectrum visualization and analysis software tool that can be downloaded from the X COM website www xcomsystems com Also available on the web site is a demo guide for Spectro X RF Editor provides a broad range of frequency domain modifications and can specify the relative time position of each spectrum segment that will be combined in to a new single spectrum file Ten tracks are available for time domain positioning working in a manner directly analogous to audio and video editing tools This allows a precise selection of the start and stop time of each waveform segment Also it displays how they overlap and combine in the frequency domain The duration of recorded data can be shortened or lengthened segments can be concate nated filtered and shifted in frequency Once all waveform segments are placed in the time domain a new composite waveform f
