Firmware Release Notes
of timing jitter.
• Separation and display of jitter components. Adds the pull down graphical display area.
• Save and recall of jitter memory. For use with jitter analysis data.
Defects Fixed
• Improved Touch Screen calibration for 86100C
• Fixed a debug assertion related to 54754A differential reference plane calibration
• Fixed a problem with saving an Instrument setup file on top of an existing setup file
• Fixed TDR remote command problem: If the right module is set to ON4 and TDTdest is
Channel 3 and you issue the command to turn on both 3 and 4 an assertion error happens.
The exact command was :TDR4:STIM ON3AND4;RESP3:TDTDest CHANNEL1
• Fixed problem with normalization of 54753A TDR module
• Fixed incorrect differential normalization (risetime of second channel). This was only
broken in revision 3.06.
• Fixed a function that returns whether the TDR stimulus is differential/common mode or
not. The incorrect value was returned if two TDR modules were installed and the right
module was differential or common mode.
• Fixed a problem when using two TDR modules. Previously, when the command
TDR2:STIM ON2 was followed by the command TDR2:STIM OFF, the left module was
correctly turned off. However the right module was then inaccessible.
• Fixed problem where differential TDT cal data was not being saved and recalled correctly
• Fixed defects that were causing normalization cal data to be invalidated unnecessarily
• Fixed problem where TDT reference plane was lost when switching between stimulus
channels
• Fixed defect where instrument could hang with the following command sequence in TDR
mode: *rst;*cls;:autoscale;*opc?
• Fixed a problem with repetitive remote loading of instrument setup files
• Fixed a defect in the code that loads TDR/TDT cal data files. TDT data was being loaded
but not fully resolved as valid.
• The :DIGitize command now works correctly with RESPonse<N> parameters. To digitize
differential responses the type of each response must be specified by turning on the
response before executing the :DIGitize command.
Known Issues
• 86119A (Optical Sampling Oscilloscope) is designed to work on software versions A.03.06
and A.03.05 only.
A.03.06 Release Notes, October 30, 2003 (Differences from Release
A.03.05)
New Feature List
•None
Defects Fixed
• Differential normalization was not working correctly because each stimulus channel was
using a different risetime value. Both channels now share the risetime setting of the first
channel.
• Stopped circular dependencies that were causing autoscale to hang.
• Function that returns if TDR stimulus is differential/common mode was broken when two
TDR modules were installed and the right module had differential or common mode
stimulus. This prevented the :DIGitize remote command from working.
• Set of valid choices for the other module is now set correctly when turning off stimulus of
