Output Setting Options
The
Output Settings
dialog bar enables the user to set the units of measure, such as milliwatt or
microwatts, for optical measurements. Pass/fail limits for optical power, modulation and rise and
fall time measurements are accessible through this selection.
To access the
Output Settings
, select the
Output Settings
button on the Dialog Bar. Select the
appropriate optical settings from the drop-down menus or enter the desired value into the
available data fields. The following output settings are available when a specific “Protocol” on
the Acquire Options menu has not been selected. The settings are preset when a specific
“Standard” has been selected (see Appendix C).
Power units
-
Select from units of dBm, µW or mW for all power
measurements.
Average power limit
-
Pass-Fail limit value.
(The minimum average optical power limit, specified
in [power units])
Modulation Measure
-
Select either "extinction ratio" or
"optical modulation amplitude". See Appendix A.
Modulation units
-

Modulation limit
-
Pass/Fail limit for modulation.
(The minimum average extinction ratio or OMA (as
selected), specified in [modulation units])
Rise Time limit
-
Pass-Fail limit for rise time measurement.
(The maximum rise time in picoseconds)
Fall Time limit
-
Pass-Fail limit for fall time measurement.
(The maximum fall time in picoseconds)
Select any of the devices on the list to display the current settings.
