O/E Module MN4765B OM PN: 10410-00742 Rev. H 1-1
Chapter 1 — Overview
1-1 Introduction
The MN4765B is a characterized, unamplified photodiode module. It is used
as an optical receiver with the Anritsu MS464xB and MS4652xB Series
VNAs to perform highly accurate and stable optoelectronic measurements of
both modulators (E/O) and photoreceivers (O/E). Bandwidth and wavelength
coverage depends on the option selected when the module is ordered. The
MN4765B allows error-corrected Transfer Function, Group Delay, and
Return Loss measurements of optoelectronic components.
Throughout this manual, the terms MN4765B and O/E Calibration Module
will be used interchangeably to refer to the MN4765B.
The MN4765B is also part of the VectorStar-based ME7848A series of
Opto-electronic Network Analyzer systems. This system packaging (-0200
versions also include an E/O Converter) allow higher level testing and
specifications to be provided for O/E, E/O and O/O measurements.
1-2 MN4765B Characterization
The accuracy and longevity of any characterization depends on the ability to
take care of the module, especially the connectors. Understanding the
maximum rated specifications and performing proper cleaning of the
electrical and optical connectors is essential.
Characterization
The MN4765B module is serialized and comes with a characterization in
relative magnitude and phase with a specified uncertainty from 70 kHz up to
110 GHz (depending on the option ordered). A copy of the characterization
can be found on the USB memory device that ships with the module. If a
replacement copy of the characterization is required, contact Anritsu
Customer Service at: www.anritsu.com

1-3 Calibration Options Overview
Re-characterization
The MN4765B calibration certificate contains the recommended calibration
interval. Any module outside of its calibration interval should be sent to
Anritsu Customer Service for re-characterization. The Anritsu Calibration
Lab will check the re-characterization against the original specifications.
1-3 Calibration Options
Standard Calibration – Option 98
Standard Calibrations provide a Certificate of Calibration which certifies
that the product has been calibrated in compliance with a quality system
registered to ISO 9001:2000, and in compliance with ISO/IEC 17025-2005,
and ANSI/NCSL Z540-1-1994 (R2002). It lists the measurement standards
used in the calibration of the new equipment, the test procedure and its
revision, as well as the environmental conditions.
Premium Calibration – Option 99
Premium calibration includes everything provided with a Standard
Calibration (above) plus test data showing actual measured values. The test
data provided varies by product complexity.
