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, mW 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".
Modulation units - Select unit of measure for modulation
When extinction ratio is selected
o Ratio
o dB
o Percentage
When Optical Modulation Amplitude is selected
o Milliwatts
o Microwatts
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.
