This controller is usually a computer, but it could be a simple terminal. The manual includes a complete list of the commands that you will need to perform remote control operations with the instrument. The manual has two main parts: Part One, “About Remote Control,” covers the principles of remote control and offers practical examples. Part Two, “Commands,” describes each of the remote control commands and queries for instrument operations. It starts with two special indexes that list the commands by short name and by category. Use these to find the command or query you want to use. As an additional guide, each chapter is prefaced by a summary of its contents. Watch for these icons and the information they signal: T TI IP Ps s offer additional hints on how to get the most out of instrument actions or features. N NOOT TE Es s bring to your attention important information you should know. Example - Important Note for users of other LeCroy DSOs Existing software: Although the X-Stream family of instruments makes extensive use of Automation interfacing, enabling many powerful means of control, most of the commonly used r
