1 Introduction

The sat-nms PowerSensor manufactured by SatService GmbH is a measurement tool which measures the

RF output power of 14 or 6GHz satellite communications signals and provides this information both on a

web page via an internal web server or as M&C output information for control systems.

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

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: T he 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

a description of the power sensor's electronic concept and the methods of linearization 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.
