TEST & MEASUREMENT APPLICATION NOTES AND WHITE PAPERS

• RF Test Setup For Measuring Power & Harmonics

  Power measurement is accomplished by using a high-power calibrated coupler or attenuator, which gets attached to the Amplifier RF output connector. Harmonics are recorded similarly by increasing the input drive from the signal source. 

• How To Configure Generic Devices In R&S Elektra

  R&S ELEKTRA is able to communicate with many devices. Still, it is impossible to integrate drivers for all devices. Hence, R&S ELEKTRA offers the possibility to integrate any device by configuring a generic driver.

• Directivity And VSWR Measurements: Understanding Return Loss Measurements

  The characterization of microwave networks requires discriminating between forward and backward traveling waves. Unfortunately no directional device is perfect, leading to potentially dramatic measurement errors. In this note we show that return loss and VSWR measurements are greatly complicated by the finite performance of the directional device used to measure the reflected power.

• 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.

• Selecting Your Next Oscilloscope: Why Digital Triggering Matters

  Many people tend to overlook the importance of triggering while selecting an oscilloscope, but it's actually a crucial factor to consider. Digital triggering can offer some significant advantages.
