TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• RF Amplifier Output Voltage, Current, Power, And Impedance Relationship

  How much output voltage, current, and power can you expect from your amplifier? In rare cases, this can be answered by applying Ohm’s law, assuming that the net power or power delivered to the load is the rated power output of the amplifier. In most cases, practical issues such as VSWR and forward power concerns must be considered before applying Ohm’s law. This application note addresses this issue and discusses an approach to be used that applies actual test data when calculating output parameters.

• Certium VCS Test System For Aircraft Manufacturers

  New aircraft need to have their radiocommunication systems tested with compact voice communication systems like CERTIUM VCS. This is cost-effective, space-saving, and scalable thanks to its IP-based infrastructure.

• Speeding Up Reflection Measurements On Antenna Systems

  Reflection measurements are a common way of assessing antenna system performance. When a minimum amount of the transmitted signal is reflected, it indicates that the transmission energy can reach the intended coverage. Undesired high reflection causes the system to be inefficient and can damage components. This application note presents solutions for aiding fast and efficient reflection measurements on antenna systems to get it right the first time.

• An Introduction To Direction Finding Methodologies

  All direction finding methodologies are meant to determine the physical or geographical location of a source of radio frequency energy. The choice of an appropriate direction finding methodology to use for a given application is largely a function of the target signal's characteristics, such as frequency and modulation, but is also influenced by the propagation environment as well as cost and complexity.  Recent advances in the development of hybrid direction finding methodologies attempt to overcome some of these restrictions and increase accuracy by using a combination of methodologies.

• AC-DC Converter Testing Fundamentals

  AC-DC conversion stage in front of any electronic equipment is needed. For this purpose, different solutions exist to convert the higher AC voltage to a lower and safe DC voltage.
