Virtually all antenna analyzers include both return loss (RL) and SWR displays that measure the quality of a transmission line or antenna. Those experienced in network and circuit analysis can easily switch between the two, but others may still be learning about RL. RL and SWR are both ways ...

So, in summary, we express insertion loss in decibels, and it is the ratio of incident power to transmitted power. Furthermore, we can summarize that return loss, which we also express in decibels is the ratio of incident power to reflected power. Therefore, we can see how the two type...
Return loss is the loss of power in the signal returned/reflected by a discontinuity in a transmission line or optical fibre.
impedance can match a source and load with different resistance and reactance values. Obviously, these calculations can become quite involved and most engineers resort to a Smith chart, a computer program or perhaps the most common method, trial and error with a SWR meter or return loss bridge!
This paper describes the procedure for using a reflection bridge (a/k/a “return loss bridge”) to manually measure return loss (easily converted to SWR if desired). “Manual” means we don’t have all the automation of a vector network analyzer, and we also can’t utilize elaborate ...

RF SWR Bridge 0.1-3000MHz Return Loss Bridge Reflection Bridge Antenna Analyzer VHF VSWR Return Loss Specification: Working Frequency: 0.1-3000 MHz Return Loss: more than 35 dB Connectors: SMA Size of the board: approx. 45*90mm Features: 1.With this known RF SWR Bridge board, you can measu...
By connecting the output of the noise source to the SWR-bridge input, and the antenna to the DUT port the return loss or SWR of the antenna can be measured with the Airspy. To get a wider than 10 MHz view of the spectrum Anders uses the SpectrumSpy software for the Airspy which is ...
