N1010A FlexDCA and 86100A/B/C/D
Firmware Release Notes
A.02.01)
New Feature List
• New Return to Zero measurements
• Added math function MIN/MAX
• Added JPEG and TIFF File Support
• Added scope measurements Vavg, Tmin, Tmax, Tedge, Delta Time
• Added Histogram Measurement Peak
• Ability to Show Histograms Window Boundary at all times when Histograms
feature is turned on
• Added remote command to save screen image to hard or networked drive
• Added remote command to save file in any supported format
Defects Fixed:
• DCA crashes after default setup while in TDR mode
• Remote command :MARKER:Y1POSITION? now correctly returns answer in volts
or ohms
• Resolved measurement resolution issue, introduced in version A.02.01. In Eye
Mode on electrical channels the vertical scale resolution was fixed at 10 mV.
• Fixed text on Limit Setup button doesn't reset
• Filter rate values displayed correctly now
• Instrument Hangs when trying to move Y- Axis Markers
• Waveform colors no longer changed when invert waveform background color is
selected
• Mask save screen command no longer overwrites previous data
• The remote command :MTESt:SCALe:SOURce query now returns SCPI standard
character text, e.g. "CHAN1"
• Fixed a release assertion problem when mapping a Sun Unix drive
• Disk error message addressed because file overwriting itself
• Long Filenames entered from File\Save menu causes problem
• Waveform memory2 tab highlighted but information is about Waveform memory1
• Resolved a problem with mask load & reset after print causes illegal op &
shutdown
• Fixed Display Data Query in INVERT format & printout showing non- invert
• Measurment Results Duplicate entry in Setup & Info
• Fixed remote command :DISPlay:LABel causes DCA to freeze in some remote
sequences
• Can't format floppy drive when full of waveform files
• Signal goes to the bottom of screen at various vertical scale settings i.e. 6.1mV/div
• Fixed remote command :WAV:FORM WORD;SOURC CGR;DATA?
Measurement Enhancements
Improved built in Jitter measurement. The algorithm now uses a smaller window (3 pixels high)
about the crossing point of the eye.
The EYE measurement is based on the histogram database.
In the case of jitter measurement, we need a "window" with vertical boundares of [y1,y2] and
horizontal [x1,x2]. The jitter value is simply derived from the histogram within this window, e.g.
the jitter RMS is the standard deviation of the histogram. The smaller the window, the smaller
the jitter.
In firmware versions previous to A.02.10, 5% of the [Ymax,Ymin] is used, assuming that the
"crossing" position is Ycross,
then
