OTDR Measurement Function

Distance measurement

Displays up to eight digits of the relative one way direction between two arbitrary points on the trace.

Loss measurement

Displays one way loss in steps of 0.01dB to a maximum of 5 digits. Displays the one way loss, loss per unit length, and splice loss between any arbitrary points on the trace.

Return loss measurement

Measurement return loss and total return loss of a fiber cable or between two arbitrary points on the trace.

OTDR Analysis Functions
