Page 68: Appendix G: Radio Frequency Basics
Appendix G: Radio Frequency Basics This section summarizes changes made in current product version. What is dBm? Radio Frequency (RF) power is measured in milli-Watts (mW) or, more usually in a logarithmic scale of decibels (dB), or decibels referenced to 1 mW of power (dBm). Since RF power attenuates as a logarithmic function, the dBm scale is most useful. -
Page 69: Fade Margin
Appendix G: Radio Frequency Basics Typically the noise floor will be lower than the receive sensitivity of your radio, so it will not be a factor in your system design. If, however, you‟re in an environment where high degrees of RF noise may exist in your frequency band, then use the noise floor figures instead of radio receive sensitivity in your calculations. -

Appendix G: Radio Frequency Basics Radio manufacturers advertise “line of sight” range figures. Line of sight means that, from antenna A, you can see antenna B.

Page 73: Glossary
Glossary Analog to digital converter. Analog Input (AI) An analog input is a measurable electrical signal with a defined range that is generated by a sensor and received by a controller. The analog input changes continuously in a definable manner in relation to the measured property. Analog Output (AO) An analog output is a measurable electrical signal with a defined range that is generated by a controller and sent to a controlled device, such as a variable speed drive or actuator. - Page 74 Glossary Pt100 Platinum 100 Resistance thermometers, also called resistance temperature detectors (RTDs), are temperature sensors that exploit the predictable change in electrical resistance of some materials with changing temperature. As they are almost invariably made of platinum, they are often called platinum resistance thermometers (PRTs). They are slowly replacing the use of thermocouples in many industrial applications below 600 °C, due to higher accuracy and repeatability.
