calculates and displays the return loss. Thorough built-in functionality provides the correct coupling and detection ratios and eliminates the effects of dark current and residual backscatter in the instrument setup to provide accurate measurements over a wide dynamic range.
The Return Loss modules can be used in any 816x Lightwave mainframe and an external fixed-wavelength or tunable laser source. The performance and usability is enhanced by combination with a Keysight power sensor in the 8163B mainframe for simultaneous RL and insertion loss measurements, especially in combination with the 81610CC calibrated reference cable. Automated use is supported by the 816x Plug&Play Driver, which also supports use of the module for advanced swept-wavelength RL measurements.
