Option 100 Jitter Software. Enabled 86107A precision time base to work in jitter
mode, which reduces the noise floor of jitter measurements down to 200 fs in
most circumstances.
• Enhancements for 86100A/B/C Mainframes: Allow the 86107A precision time base
modules to operate over continuous frequency bands. No hardware upgrade
needed to existing modules, but customers must either provide their own filter or
a clean sine wave with low total harmonic distortion.
Defects Fixed
• Repaired remote rise time measurement always returns data from lowest channel
• Fixed Remote Command to measure Extinction Ratio Factor (:MEAS...:ERF)
• Resolved Differential TDR Inverted channel marker values reporting incorrect
value
• Addressed Auto Scale incorrectly aligns in time when multiple waveforms present
on screen. There is now an optional bit rate parameter for the ":AUToscale" remote
command. If bit rate information provided remotely, autoscale is much more
robust (and much quicker!). Note that this parameter only applies to NRZ eye
diagrams and clock signals.
• Repaired start of mask test aligns immediately even without sufficient data.
Alignment will now be postponed up to 5 seconds if there is not enough data to
align.
• Added remote command for reading TDR excess reactance. Added
:MARKer:REACtance query command. It returns the value as follows:
<reactance_value>,<units> where reactance value is in scientific notation and units
are F or H. When there is no reactance value, a value of zero is returned and
units of F.
• Repaired the remote command Disk:Simage to Network drive breaking after
excessive calls because a network drive resource was being opened and not closed.
• Fixed error in Scope Measurement - :MEASure:DELTatime [source][,source]].
Instrument behavior is now consistent with documentation.
• Resolved Channel Input- Autoscale failed to send error message on marginally large
signals. The correct notification occurs now for clipped signals.
• Repaired Horizontal scale being incorrect for clock signals while in jitter mode by
adjusting the scales properly.
• Repaired remote command :System:DSP cmd with parameter '%' or '?' does't seem
to work by fixing the instrument parser to recognize some more special characters.
• Fixed color pallet being incorrect when screens are saved in .JPG mode.
• Resolved ?eControl at limit error?f showing up when loading old setups by fixing
the setting with the screen savers. There was a difference between 86100A/B and
86100C setups.
• Resolved Scope Measurement - :MEASure:TMIN returns Err: - 224,Illegal parameter
value.
• Repaired Channel Input - :CHAN:FDES? does not return Headers when
:system:header on
• Changed default gain settings for 86117A Module Initialization to improve field
servicing
• Fixed remote command Trig:Plock:Autodetect turns off pattern lock if autodetect
fails
• Corrected Color grade incorrect when loading database memory in oscilloscope
mode
• Repaired Histogram - Measure:Histogram:ppos?returns 9.99999E+37 while in TDR
mode
• Fixed STM64_OC192SuperFEC_12_5.msk mask file. It should be a scaled version
of the STM- 64 OC- 192 mask (rectangular, not hexagonal).
• *OPC now operates properly in Jitter Mode. *OPC, OPC? and *WAI should work
N1010A FlexDCA and 86100A/B/C/D
