Explanation

Return Loss

• If “

<” is displayed next to the return loss value, the measured waveform is saturated. If the waveform

is saturated, the actual reflection value is larger than the value shown. To prevent a waveform from
being saturated, you can:

•  Select a large attenuation value, and perform the measurement again.
•  Select Hi-Reflection for the average method, and perform the measurement again.
•  Select a large pulse width value, and perform the measurement again.

• When reflections are small (less than or equal to about 0.5 dB), the return loss is not displayed.
