WARRANTY
Teledyne LeCroy warrants this oscilloscope accessory for normal use and
operation within specification for a period of one year from the date of
shipment. Spare parts, replacement parts and repairs are warranted for 90 days.
In exercising its warranty, Teledyne LeCroy, at its option, will either repair or
replace any assembly returned within its warranty period to the Customer
Service Department or an authorized service center. However, this will be done
only if the product is determined by Teledyne LeCroy's examination to be
defective due to workmanship or materials, and the defect is not caused by
misuse, neglect, accident, abnormal conditions of operation, or damage
resulting from attempted repair or modifications by a non-authorized service
facility.
The customer will be responsible for the transportation and insurance charges
for the return of products to the service facility. Teledyne LeCroy will return all
products under warranty with transportation charges prepaid.
This warranty replaces all other warranties, expressed or implied, including but
not limited to any implied warranty of merchantability, fitness or adequacy for
any particular purposes or use. Teledyne LeCroy shall not be liable for any
special, incidental, or consequential damages, whether in contract or otherwise.

OE695G Overview
The OE695G is designed to help troubleshoot optical-to-electrical signal integrity
issues at the board level. For system integrators who measure both electrical
and optical signals in their products, the OE695G provides electrical
measurements on optical signals, while taking full advantage of the Teledyne
LeCroy real-time oscilloscope tool set and the debugging capabilities of the
Teledyne LeCroy Serial Data and Crosstalk Analysis software options.
When connected to the oscilloscope, the OE695G becomes an integrated part of
the oscilloscope. Power is supplied to the OE695G by the oscilloscope (no
external power supply is needed), and the OE695G communicates to the
oscilloscope its identity and scaling information. The Optical Wavelength, Dark
Calibration and Reference Receiver functions are all controlled from the
oscilloscope’s user interface.
The OE695G is unique in that it operates with a real-time oscilloscope, not a
sampling oscilloscope, and uses a digital signal processing (DSP) filter to enable a
user-selectable reference receiver response. Since the optical input signal is
input to a real-time oscilloscope, it is possible to use the contiguous data
acquisition of the real-time oscilloscope to obtain serial data pattern knowledge
and provide Tj, Rj, and Dj decomposition to very high accuracy, like what is done
with high-speed electrical serial data signals. The low cost and general utility of
this optical to electrical converter makes it ideal for those who are already using
real-time oscilloscopes for electrical serial data measurements, and need to also
measure optical serial data signals as well.
Compatibility
The OE695G converter is compatible with WaveMaster/SDA/DDA 8
Zi/Zi-A, LabMaster 9 Zi-A, and LabMaster 10 Zi series oscilloscopes using
Teledyne LeCroy’s 2.92mm interface and Teledyne LeCroy’s ProLink
interface through the use of the LPA-2.92 ProLink to 2.92mm adapter.
Requires 6.9.0.0 or later version of Oscilloscope firmware.
