Measuring signal eye.
Tektronix recommends using a Tektronix DPO70000 series
or DSA70000 series oscilloscope with a P7500 series probe with solder-down tips
for most accurate results. If your system does not allow you to use solder-down
tips, use the handheld Precision Differential Probing Module (Tektronix part
number P75PDPM). Tektronix recommends using TDSJIT3 Advanced software
to take signal eye measurements. Tektronix RT-Eye software is also acceptable.
For instructions on using TDSJIT3 Advanced and RT Eye software, go to
Tektronix.com/manuals, or contact your local Tektronix representative.

P6700 Series midbus probe circuit impact.
Tektronix has provided two
Touchstone® models (P67xx_wop.s2p and P67xx_wp.s2p). (See page 75,
.) These models simulate the impact of the P6700 Series
midbus probe (8 or 16 channel) retention mechanisms with and without the
probe installed. This is actual S-parameter measured data using real probes and
retentions. Graphical representation of the data is provided in the next two graphs.
The
fi
rst graph shows the frequency response of a transmission line loaded with a
P6700 midbus probe retention. (See Figure 37 on page 37.)
