N1010A FlexDCA and 86100A/B/C/D
Firmware Release Notes
differential mode normalization to enable faster edges.
• Support for InfiniiMax II Series Probe
• Enables calibration debugging for module vertical calibration.
• Adds a method for stabilizing RJ value for jitter measurements. Remote commands
added for RJ stabilization capability (#200).
• Determines linear feed forward equalizer tap values automatically (#201)
• Adds support for 8xFibre Channel filter rate (86105C #197)
General Firmware Defects Fixed in 4.20
• Repaired probe calibration date disappearing after autoscale or probe calibration
on other channel.
• Fixed autoscale with no channels turned on does nothing. Autoscale now displays
a dynamic text area message when autoscale is performed with no channels
activated.
• Repaired autoscale with limit test activated causing software to hang.
• In TDR mode, fixed (:TIM:RANG 6.0E- 001 and :MARK:STATe X1Y1,MANual,TRACk)
remote commands sent quickly in succession causing a software crash.
• In TDR mode, resolved transducer settings are not always correct. Channel units
picks are now fixed.
• In TDR mode, delta marker units track channel units, not marker units. This has
been resolved.
• Repaired TDR normalization problem with center time reference. Responses are
now being recalled even if reference is set to 'Center'.
• In TDR mode, resolved normalization staying valid after channel vertical
calibration is performed.
• Provided excess reactance measurement which was not previously available for
differential TDR responses.
• Added a remote query to see if TDR normalization is valid over GPIB.
• In TDR mode, fixed Ohms scale not available on Channel 2 after default setup
• Repaired extinction ratio calibration failing after precision time base is enabled.
Extinction ratio calibration could fail with precision time base on if the horizontal
scale was set for less than one period of the reference clock on screen. The
calibration has been modified so that at least one period of the reference clock is
on screen when dark level data is measured.
• Resolved oscilloscope hanging with 86107A when limit test is turned on. Disabled
acquisition limit when setting the precision time base time reference. Hang no
longer occurs.
• Resolved broken time base calibration. Hardware was left in an inconsistent
setting relative to the control system, causing the next calibration to fail.
• Repaired ASSERTS when dialog is opened and DCA application is minimized.
When minimized, application will be maximized on all front panel events (button
press or knob movement) before event is processed.
• Repaired turning on of pattern lock after undo default setup with 86107A.
Changed how the valid setup is built to account for priorities of controls for
pattern lock and precision time base.
• Resolved application hang from Setup file load with divided trigger on.
Reorganized acquisition limit display update to prevent excessive Windows
messages from being generated and added code to remote commands to gracefully
handle failure if occurs when placing windows messages. Hang no longer happens.
• Repaired release assertion during undo default setup. Fixed interaction between
recall setup, autoscale, and the auto- record length control.
• Fixed combination of TIM:BRAT + :TRIG:RBIT + SYST:MODE JITT causing
application exit
• Resolved STOP CHAN1 :TIME:RANG:MEAS:VTIM? causes abrupt application exit
• Repaired MEASure:CGR:SOUR CGMemory causing application hang
