WebThis calculator computes the VSWR, reflection coefficient, return loss and matching loss in a transmission line. Understanding VSWR and Return Loss. Return loss can be measured by using microwave and RF test equipment such as a signal generator, directional coupler along with a spectrum analyser or power meter, or alternatively by using a ... WebJan 12, 2024 · The presence of SWR can affect monitoring components used to measure power levels impacting the reliability of such measurements. SWR is the ratio between transmitted and reflected waves. A high SWR indicates poor transmission-line efficiency and reflected energy, which can damage the transmitter and decrease transmitter efficiency.

WebJul 9, 2024 · A: An SWR meter does not measure the actual impedance of a load (the resistance and reactance) but only the mismatch ratio. The SWR meter’s impedance must also match the line’s impedance (typically 50 or 75 ohms), so some SWR meters have switches or adapters that select or match the impedance. WebVSWR Calculator.
