Note

• If “<” is displayed next to the return loss value, the measurement 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 and reflection level are not

displayed.
