Calculation[edit]

The VSWR (Voltage Standing Wave Ratio) test level in RadiMation is a measurement that indicates how well the energy from a signal source is being transferred to a device under test. It provides insight into the efficiency of power delivery, with a lower VSWR indicating better efficiency and minimal energy reflection. This is important in electromagnetic immunity testing to ensure accurate power application across test frequencies.

In RadiMation, the VSWR is calculated based on the Return Loss (RL) between the forward power and reflected power.

  • Calculate Return Loss (RL):
    

In RadiMation, this is calculated as the difference between the forward power and the reflected power.

  • Calculate the Reflection Coefficient:

The reflection coefficient is a value derived from the Return Loss. It quantifies the proportion of energy reflected from the device.

    
  • Calculate VSWR:

VSWR measures the standing wave pattern created by the interference between the forward and reflected waves. It’s calculated based on the reflection coefficient as follows:

    

If the reflection coefficient is 1 (meaning full reflection with no power transfer), the VSWR is set to a high value (e.g., 1000) to represent an infinite VSWR.
