OE695G Optical-to-Electrical Converter
8 922562-00 Rev A
Input Selection for Optical Wavelength
There are four standard optical wavelength selections at 785nm, 850nm,
1310nm and 1550nm. Custom optical wavelength can be adjusted between
750nm to 1650nm; however, gain of the OE695G can vary widely at different
wavelengths, and calibration of gain is only performed at the standard
wavelengths. At other wavelengths, gain is assumed to follow a linear slope, but
this assumption will not yield the stated vertical level power accuracy
specification. However, the overall signal fidelity will still be maintained.
Warning Messages
These messages may appear during operation with an oscilloscope.
Warning Message Explanation
XML data not found Warns that the XML file containing additional
information regarding calibration of the probe is not
present, and the probe would work in only a very limited
way. If you see this message, stop using the probe and
contact Teledyne LeCroy for support.
Nominal reference
receiver response applied The oscilloscope channel connected to the OE695G does
not match any previously calibrated channels, therefore a
nominal reference receiver response is applied.
Calibrated reference
receiver response applied The scope channel connected to the OE695G matches
one of the recalibrated scope channels of the OE695G.
This should be the normal operation mode.
Reference receiver active
only at 10 GS/s or greater The sampling rate is too low. Enter at least the minimum
sampling rate necessary for the reference receiver.
Performance may not
meet all specifications of
standard. Calibration
temperature (TEMP ) The temperature at which the probe was calibrated and
the temperature of the connected probe are different.
TEMP would be replaced by the calibration temperature.
Temperature changed
since last Dark Calibration
recommended The Dark Calibration temperature and the current probe
temperature are different.
