1 Introduction

The sat-nms PowerSensor enables the sat-nms software to perform a precise power measurement even if the monitored and controlled SATCOM equipment like TWT or SSPA amplifiers or converters do not provide the necessary capabilities or don't have the accuracy. Applications which include a transmit power control loop need to measure the transmit amplifier output power. While many amplifiers provide a built in power sensor with adequate accuracy and resolution, some low-cost models do not. This power sensor is intended to be a supplement to such equipment.

This user manual contains all necessary information how to install, setup and operate the sat-nms PowerSensor. The user manual is available as a printed document and for on-line reading on the power sensor itself as well.

The paragraphs below give a short overview to the contents of this manual.

• Installation : The installation chapter guides through the installation and setup of the power sensor. It describes the mechanical concept of the power sensor box and the assignment of the power sensor's connectors. Finally you learn in this chapter how to set the power sensor's IP address, which is a essential precondition to operate the power sensor by means of a web browser.
• Operation : The sat-nms power sensor is operated using a standard web browser like the Internet-Explorer on MS Windows based computers. The user interface design is straight forward and clearly structured. Operating the power sensor is mostly self-explanatory. Nevertheless, the 'Operation' chapter outlines the map of web pages which make up the user interface and elaborately describes the meaning of each alterable parameter.
• Remote Control : The power sensor provides a versatile remote control interface. A monitoring & control software may fully operate the power sensor through a TCP/IP network connection. This chapter describes the communication protocol used for remote control and lists all parameters accessible through the remote interface.
• Theory of Operation : This chapter gives a short overview how the power sensor works. This includes a description of the power sensor's electronic concept and the methods of linearizion and temperature / frequency response compensation implemented in it.
• Specifications : At the end of the document, the specifications applicable to the sat-nms power sensor are summarized in this chapter.
