SECTION 3 – Setup and Measurement
This section describes the set-up of the
OE-2 and provides instructions that enable the user to
take a quick measurement for rapid familiarization with the instrument.
In addition, this section describes the Virtual Instrument Signal Integrity™ (VISI) software tools
necessary for using the
OE-2 with any WAVECREST measurement instrument. Please refer to
the VISI User’s Guide for detailed definitions and instructions of this and other VISI tools.
Test System Requirements
To use the OE-2, a complete test system consisting of the following components is needed:
• A
WAVECREST OE-2
• A WAVECREST SIA or DTS (PC or Workstation with VISI installed) instrument
• A source of optical signals
• Interconnecting cables
Before attaching any connector to the
OE-2, clean all optical connections using
an optical fiber connector cleaner such as the NTT-ME CLETOP.
To prevent damage to the optical-to-electric (O/E) input connector, a build-out connector is
included with the
OE-2. The build-out connector can be replaced if it becomes damaged or dirty.
A dirty or scratched O/E input connector can severely degrade the input signal, resulting in
inaccurate measurements.
NOTE: If the O/E input connector is damaged, the instrument must be returned to
WAVECREST
for repair.
Before Using the OE-2
To ensure the highest accuracy and proper GPIB operation, it is important that:
 All OE-2’s are warmed up for at least ½ hour prior to taking a measurement.
 All OE-2 GPIB addresses have been correctly assigned (see page 8).
 An external calibration of the OE-2 is performed at least once each day (see page 12).
The
OE-2 should also be recalibrated if there has been a change of more than 5 C° in
ambient temperature.
Instrument Setup
 Attach the power cord to the back of the instrument and to an appropriate power source.
See Appendix A for specific power requirements.
 Attach the cleaned build-out connector to the OE-2 input.
 Attach the cleaned input signal cable to the build-out connector.
 Turn on main power on the back of the unit.
 Turn on front power switch. The front switch is typically used for daily operations and
also allows easy access to power if the unit is mounted in a rack.
