Presentations
Evaluating errors and uncertainties in RF & microwave measurements
This talk gives an overview of the principles and processes involved in dealing with errors in measurements, particularly at RF and microwave frequencies. The talk shows how the concept of uncertainty can be used to quantify the effects of errors that occur during measurements. The methods used to evaluate and express uncertainty are described and illustrated with some simple practical examples. The purpose of this talk is to enlighten rather than mystify the subject of dealing with error and uncertainty in measurement.
All you need to know about RF and microwave coax connectors but were afraid to ask
The humble coaxial connector has been a regular player in the high frequency electronics industry for the past fifty years or more. But it is this apparent familiarity, and apparent simplicity, that often leads to misunderstandings and mistakes with the use of connectors. This talk will give a review of coax connectors with an emphasis on how to get the most from any given connector. The talk begins with an historical overview of the evolution of the coax connector right up to the present day. The dos and don’ts of using connectors will also be addressed and how to select the best connector for a given application. Finally, some tips will be given on how to keep connectors in good health and how to ensure long connector life.
