Agilent Technologies 86100A Release Notes page 35

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
