Select the channel to view. (“Channel” refers to the DTS or
SIA
channel.) The software will poll the
OE-2
configured to that channel
to determine which filter bank options are installed.
WAVECREST
’s
VISI
software has preprogrammed set-ups for several
popular communication standards, including Fibre Channel, Gigabit
Ethernet, and Infiniband. When you select one of these filter set-ups,
VISI
will automatically select the filter and amplifier in the
OE-2
and
set the wavelength for measurements. In addition,
VISI
will set
measurement limits from the standard’s requirements such as rise and
fall time, extinction ratio, optical modulation amplitude and average
optical power. A Pass or Fail message will appear on the
VISI
display
indicating whether the signal satisfies the standards limits. The default
values for the preprogrammed settings are listed in Appendix C.
Select the “Standard” drop-down menu. Standards corresponding to
the filters installed in the
OE-2
will be listed in the “Standard”
window. For example, if the
OE-2
has filter option 1, with Fibre
Channel, Gigabit Ethernet and Infiniband filters installed, those
standards will appear in the drop-down list.
Select a protocol from the drop down menu in the “Protocol” field for
the type of signal to be measured. The protocol identifies the sub-
section of the communication standard. Once the standard and
protocol are selected, the preprogrammed settings will be shaded,
preventing you from changing them.
If “User-Defined” is selected, all settings and limits may be selected or changed.
Select
(RUN) and
VISI
will continuously make measurements.
If the signal level is too low, the gain of the
OE-2
amplifier can be increased in the
Amplifier window.
