Firmware Release Notes
precision timebase. Previously, the combination of these required three separate
modules. Now they are incorporated into a single, double wide module.
• Support for reference receiver options 86116C- 025 and 86116C- 040. The 86116C
has been replaced with the 86116C- 040 and 86116C- 025. Option 040 is a direct
replacement for the legacy 86116C as a reference receiver for 39.8 GB/s and 43.0
Gb/s NRZ signals. Option 025 offers reference receiver capability for 17, 25.8 and
27.7 Gb/s NRZ signals which were previously not available in the 86116C.
• Support for the 86100CU- 400 PLL / Jitter Transfer Analysis option.
• Support for the Bulk Optics change on the 83496B Clock Recovery Modules.
• 86108A Setup Wizard to help configure the 86108A module. This wizard has preset
configurations for a number of use cases to make the configuration as simple as
possible.
• Advanced Clock Data Recovery Setup for the 86108A allowing user to specify Type
2 Transition Frequency (peaking) of the loop.
• Support for MATLAB measurements with scripts created by the user. Now the
user can make custom measurements on the DCA. These measurements run just
like internal measurements, with results on the Measurement Tab, including
statistics.
• Improved jitter measurement accuracy for very large jitter. Increased limit for
maximum amount of measureable jitter.
• Added Large Jitter Mode for extending jitter measurement capabilities. This mode
is enabled when the amount of jitter exceeds the transition time of the signal. As
with the
• new edge model, Large Jitter Mode will also increase the accuracy of large jitter
measurements and increases the maximum amount of measureable jitter.
• New S- parameter plots, phase and group delay, for 86100C- 202 Enhanced
Impedance and S- Parameter Software package.
• Auto Mask Margin is a new enhancement to the Eye Mode Mask Margin feature
which will search for a scaled mask that matches a user specified bit error rate.
• Auto Relock is a new feature for clock recovery modules. Previously, when a
recovered clock had lost lock, the user would have to manually relock. The 8.0
release now has the functionality to do this automatically.
• Users can now send remote commands to the instrument directly over Ethernet
LAN. GPIB is no longer required for remote operation.
• Increased the maximum record length from 4,096 to 16,384.
• Now ?gPattern Lock?h on 86100Cs with option 001 removes the 4 ns
discontinuities on long spans (no time tears) as long as the trigger delay is at or
close to its minimum value. In this case the instrument synchronizes the timebase
to the pattern and force samples to be taken at the correct locations.
• Increased the maximum timebase range while using Pattern Lock from 250.0 ns/
div to 250.0 us/div.
• Increased the speed of the Pattern Waveform Save feature.
• Reduced the minimum points/bit of Pattern Waveform Save from 16 to 1.
• Added support for Trigger Divide Ratios of 1:18 and 1:36.
General Defects Fixed
• XY Verbose values now correspond to the values being shown on the display with
account for the reference plane.
• Fixed crash that would happen when attempting to run the Linear Forward
Equalizer from a MATLAB script which was not available.
• Fixed issues with changing the trigger source while precision timebase is on.
• Fixed two issues referring to DTA messages complaining about precision timebase
issues. One would complain about the time reference being out of band when the
precision timebase was not on, and the other message would ask user to restore
reference clock after long continuous usage of Pattern Lock and precision
