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 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.
Design Of A Complete RF Downconverter Module For Test Equipment
The example module and its constituent parts were designed and simulated with AWR Design Environment software using circuit- and system-level analyses. The integration of the downconverter within a mechanical outline influences the layout of the individual radio blocks.
Waveform Acquisition Rate And Why It Matters
Explore key specifications of modern digital oscilloscopes, including often overlooked ones like acquisition rate and blind time, to better understand their importance in oscilloscope applications.
Testing For Coexistence In Crowded And Contested RF Environments
In this paper, we review some of the key research, development, test and evaluation (RDT&E) challenges that arise when developing and deploying systems that need to operate in congested and/or contested RF environments.
