Firmware Release Notes
2 only or 4 only. Differential TDT data was not being saved and recalled properly.
• Normalization cal data was being invalidated inconsistently and unnecessarily when TDR
settings were changed.
• Differential normalization behavior was based on the current setting of the differential
mode control and not on the setting at the time the cal was performed.
• Fixed a bug where you would get "Control is set to limit" error messages the first time you
power up an instrument.
• Single-ended TDT normalization data is now recalled properly when loading a TDR/TDT
cal file. Previously the normalization cal data was read from the file but not fully resolved
as valid.
• Enhanced TDT normalization so that thru measurements from calibration are stored
independently from TDR short measurements. This allows greater flexibility in switching
between stimulus channels.
• Fixed threading synchronization problem that caused the instrument to hang under
certain conditions when a setup was recalled remotely.
• The :DIGitize remote command now works properly with RESPonse<N> parameters. If the
response is differential or common mode it must be turned on before executing the
:DIGitize command.
A.03.05 Release Notes, April 21, 2003 (Differences from Release
A.03.04)
New Feature List
• Added support for the 86119A Optical Sampling Oscilloscope
• Added support for the new N1022A probe adaptor. This probe adaptor provides support
for the InfiniiMax 3.5 to 7 GHz probes. This includes the following Agilent probes: 1131A,
1132A, 1134A, 1156A, 1157A and 1158A.
• Added support for horizontal mask alignment recommendation as per ITU-T G.691 for
STM16 mask testing. This allows the mask center region to be positioned optimally along
the horizontal axis to achieve the minimum number of mask violations. Along with this
implementation, the following mask file was added:
• STM016_G.691_V2.0.msk
• Added the following NRZ masks to support testing to the Fibre Channel Physical
• Interface (FC-PI) Rev 13 standard for the following data rates: 1063, 2125 and 4250 MB/s.
• The mask file names are as follows: FC1063_PI_R13_Dec01.msk,
FC2125_PI_R13_Dec01.msk, FC4250_PI_R13_Dec01.msk
Defects Fixed
• Improved color contrast between mask regions when saving screens with Invert
Background Color checked. Previously, the mask margins appeared to be the same color
as the mask.
• Corrected problem when loading waveform memories, scale and offset limits were
incorrect. They were too limited when channel attenuation was a large value.
• Corrected problem with dropouts on channels when in differential TDR mode.
• Corrected problem with dropouts using high bandwidth modules when in TDT mode.
• Corrected problem with signal response being clipped when performing a differential TDR
normalization
• Corrected problem with multiple presses of Stop/Single button causing data acquisition to
halt.
• Corrected problem with Autoscale not completing when Histograms are enabled and
acquisition is stopped.
• Corrected documentation with remote Programmer?fs Guide. Had incorrect syntax for
probe calibration. Indicated command was :CAL:PROB:CHAN<n>, should be :CAL:PROB
