TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• 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.

• 5G New Radio Over-The-Air Base Station Receiver Tests

  This application note describes all mandatory RF receiver tests, according to the Release 16 (V16.3.0). It also offers a brief introduction about the different R&S OA antenna test solutions and how they are applicable for base station conformance testing.

• 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.

• Accurate Test Fixture Characterization And De-Embedding

  This application note provides practical hints to accurately characterize and de-embed these lead-in and lead-out structures with R&S Vector Network Analyzers ZNA, ZNB, ZNBT and ZND.

• Measurement Of The Phase Between Several Signals

  Measurement of magnitude can be done with spectrum analyzers, power meters etc. For a phase measurement, a VNA is the easiest, fastest and most accurate instrument.
