this product or any products connected to it.
To avoid potential hazards, use this product only as specified.
Only qualified personnel should perform service procedures.
While using this product, you may need to access other parts of a larger system.
Read the safety sections of the other component manuals for warnings and
cautions related to operating the system.
Use proper power cord. Use only the power cord specified for this product and
certified for the country of use.
Connect and disconnect properly. Connect the probe output to the measurement
instrument before connecting the probe to the circuit under test. Connect the

Safety
This manual uses certain conventions that you should become familiar with
before attempting service.
Throughout this manual, the term module appears. A module is composed of
electrical and mechanical assemblies, circuit cards, interconnecting cables, and a
user-accessible front panel. References to a module are different than references to
products such as “Sampling modules”, “Phase Reference modules”, or “Accessory
dules”, which are products installed in the instrument compartments or on
mo
extender cables.
Symbols and terms related to safety appear in the General Safety Summary found
at the beginning of this manual.

n contains the specifications for the DSA8300 Digital Serial Analyzer.
The 82A04/B Phase Reference modules affect the DSA8300 mainframe
specifications; therefore, the 82A04/B module specifications are part of the
DSA8300 mainframe specifications.
All specifications are guaranteed unless noted as "typical." Typical specifications
are provided for your convenience but are not guaranteed. Specifications that are
marked with the
symbol are checked in the DSA8300 Digital Serial Analyzer
All specifications apply to the instrument and sampling modules unless noted
otherwise. To meet specifications, these conditions must first be met:
The instrument must have been calibrated/adjusted at an ambient temperature
between +10 °C and +40 °C.
The instrumen
t must have been operating continuously for 20 minutes within
the operating temperature range specified.
The instrument must be in an environment with temperature, altitude,
humidity, and vibration within the operating limits described in these
specifications.
NOTE. "Sampling Interface" refers to both the small module compartments and
the large module compartments, unless otherwise specified.

The published IEEE P802.3ba 40/100GbE D3.2 standard defines the Optical Reference
Receiver specifications for 100GBASE-LR4 and –ER4 variants as follows (per section
88.8.8 in P802.3ba D3.2, June 2010): a standard 4th-order Bessel-Thompson
Scalar Frequency Response with a reference frequency of 0.75x(data rate).
(0.75*25.78125 GHz=19.337 GHz)
NOTE. The table below is a discrete list of some specific values that are commonly
listed in ITU standards; curve and tolerances are actually a continuous function.

At the time of this writing the IEEE P802.3bg 40GbE task force has not yet finalized the
ORR specifications for the 40GBASE-FR serial variant. Preliminary tolerances are
chosen to match the first draft proposal D1.0 of IEEE 802.3bg released in June 2010
(Sect. 89.7.8).
The response follows a standard 4th-order Bessel-Thompson Scalar Frequency
Response with a –3dB reference frequency of 0.75 x (data rate); for example, 0.75 x
41.25 GHz = 30.94 GHz.
Tolerances are as specified for STM-64 in ITU-T G.691. The table below lists the
nominal curve and tolerances at various frequencies; based on ± 0.85 dB DC to 0.75 x
(data rate) and expanding to ±4.0 dB at 1.5 x (data rate).
The 10GBASE-W, 10GBASE-R, 10GFC, 40G BASE-R4, 100GBASE-R10 standards
specify an optical reference receiver with a 7.5 GHz fourth-order ideal Bessel-Thompson
response.
For convenience, the scalar frequency response of the output amplitude (for sinusoidal
swept optical input) has been interpreted from the published Bessel-Thompson transfer
function for 9.95328 Gb/s ITU-T Reference Receivers, and from IEEE802.3 and listed
below.

In 10GBASE-4 setting, scalar frequency response falls within industry standard,
Bessel-Thompson reference receiver boundary limits.
10GBASE-4 frequency response boundary limits are derived by simply scaling all
frequency values by 2.5X as described in IEEE 802.3z section 38.6.5 (this section
refers to ITU G.957 for tolerances).
