Fast Spectral Loss Measurement Application

The average power should serve as a verification for the reference

NOTE

validity. Depending upon the TLS power selected in the GUI and the

insertion loss of the reference connection, you should compare this value

with your expectation of the average power.

You can perform a single reference sweep on multiple ports

simultaneously by using the check boxes above the individual ports. All

checked ports will be included in the reference sweep, once you click the

New Ref. (sel.) button.

To obtain a reference on all ports simultaneously, click the New ref. (all)

button. In this case, it doesn't matter which ports have been checked or

unchecked.

Use the Select All and Select None buttons to set or remove all check

marks simultaneously.

You can obtain reference data on one or more ports, then copy those

traces to be used as reference for other ports as well or instead. To do so,

obtain the actual reference sweep, then check all destination ports (make

sure all other ports are unchecked) and click the Cpy Frm button at the

source port.

All destination ports will show the detail information of the source port

afterwards.

You can clear data for individual ports by clicking the Clear button of the

respective port. By checking several ports and clicking the Clear selected

button, reference data for those ports is cleared. By clicking the Clear Ref.

button, the complete reference data is cleared from memory. Also upon

restarting the engine, no reference will be loaded automatically, until a

new reference has been saved.

Ports that don't display reference details (such as timestamp, etc.) will

NOTE

be referenced to the TLS power set in the Measurement Parameters

section.

You can load, save and delete reference files by clicking the Load Ref.,

Save Ref. and Delete Ref. buttons. By clicking either button, a list of

reference files will be displayed to choose from.
