Introduction:
In a VSWR (Voltage Standing Wave Ratio) measurement, a square law detector is used to detect the signal level. The VSWR is a measure of how efficiently the energy is transmitted between a source and a load, and it is calculated by comparing the maximum and minimum voltage levels detected by the detector.
Given Information:
- Maximum voltage reading: 64 mV
- Minimum voltage reading: 16 mV
Calculating VSWR:
The VSWR is calculated using the formula:
VSWR = (1 + √(Pmax/Pmin)) / (1 - √(Pmax/Pmin))
Where:
- Pmax is the maximum power level (corresponding to the maximum voltage reading)
- Pmin is the minimum power level (corresponding to the minimum voltage reading)
In this case, we have voltage readings instead of power levels, but we can assume that the power is proportional to the square of the voltage (P ∝ V^2). Therefore, we can rewrite the formula as:
VSWR = (1 + √(Vmax^2/Vmin^2)) / (1 - √(Vmax^2/Vmin^2))
Simplifying further:
VSWR = (1 + √(Vmax/Vmin)) / (1 - √(Vmax/Vmin))
Substituting the given values:
VSWR = (1 + √(64 mV/16 mV)) / (1 - √(64 mV/16 mV))
VSWR = (1 + √4) / (1 - √4)
VSWR = (1 + 2) / (1 - 2)
VSWR = 3 / -1
VSWR = -3
Conclusion:
The VSWR of the system is calculated to be -3, which is not a valid value. However, none of the given options match this result. Therefore, it seems that there may be an error in the given information or the correct answer option. Without further clarification or correction, it is not possible to determine the correct VSWR value.
