86100A/B/C
Firmware Release Notes
Added additional settling time when setting the gain of the average power monitor.
• Repaired Extinction ratio calibration creating offset when 86107A precision timebase is
active. The dark level measured during extinction ratio cal is too high when the cal is
performed with precision timebase on.
• Fixed O/E calibration failing on 86105C Option 100 modules. Added an additional signal
path to allow for completion of calibration for 86105C #100.
• Added support for 86105C unfiltered path.
Known Issues
• 86119A (Optical Sampling Oscilloscope) is designed to work on software versions A.03.06
and A.03.05 only.
A.04.10 Release Notes, November 1, 2004 (Differences from Release
A.04.01)
New Feature List
• Support for 86105C Reference Receiver Module
• Provide the Enhanced Jitter Analysis Software Package (#200), which includes all
previous jitter separation measurement capability, demonstrated in #100.
• The Bathtub jitter feature consists of two parts: the ability to display a plot of the
extrapolated bathtub curve against the measured TJ histogram and the ability to select the
BER at which TJ is measured.
• Increase pattern length supported by jitter mode to 2^16
• The Jitter Frequency Analysis feature will provide insight into the frequency content of
periodic jitter. It will analyze both jitter that is correlated to the data rate (sub-rate jitter)
as well as jitter that is uncorrelated from the data rate (asynchronous PJ). The items of
interest are: jitter frequency, jitter magnitude, and relationship of jitter frequency to bit
rate (i.e. is it a sub-rate)
• Added a Frequency component shape graph. After frequency analysis is turned on, the
user will be able to display the shape of the jitter associated with a particular frequency.
This aids in the identification of complicated jitter waveforms such as square waves, which
has a large number of harmonically related frequencies.
• Added Advanced Waveform Analysis (#201)
• Built-in Linear Feedforward Equalizer application with up to 15 digital tap filter values
• Integrated MATLAB interface to allow signal processing using MATLAB (customer must
purchase and install their own MATLAB licenses separately)
• Allow the customer to save and recall pattern waveforms which are long single-valued
waveforms that span multiple bits, up to the entire pattern length of 2^23. Up to 4096
• points can be saved for each bit, which allows the file to be exported to other software
applications like Excel or MATLAB for further analysis
• Support for 86100C Mainframe
The following features are available only with 86100C mainframe:
• Added Windows XP Operating System Service Pack 2. We recommend that all existing
86100C with Service Pack 1 installed update to Service Pack 2 because the additional
security capabilities.
• The following feature is also available for 86100C mainframe and Option 001 Wide
Bandwidth Trigger. Pattern Lock ("Eyeline?h) trigger will work when an 86107A precision
time base module installed.
• The following feature is available with 86100C mainframe with Option 001 and Option 100
Jitter Software. Enabled 86107A precision time base to work in jitter mode, which reduces
