Turn your Z-Series oscilloscope
into a time-domain
transmissometry (TDT). Quickly
characterize and compensate
any input into your scope.
PrecisionProbe technology turns
your oscilloscope into the ultimate
characterization tool. Not only can you
do the normal waveform transformations
such as de-embedding through
InfiniiSim, PrecisionProbe allows quick
characterization of your entire probe
system (including cables and switches)
without the need for extra equipment.
PrecisionProbe takes advantage of the fast
“cal output” signal built into the Z-Series
to characterize and compensate insertion
loss on the measurement system.
Now every probe and cable in the system can have the exact same response — probe to
probe or cable to cable — without the inaccuracies that using one model can produce.
You can properly characterize custom probes and remove unwanted responses. In
addition to characterizing the cables, PrecisionProbe allows for immediate use on the
same instrument. PrecisionProbe saves you time and money while increasing your
measurement accuracy.
When you combine InfiniiMax probes with switches between the amplifier and the probe
head, PrecisionProbe allows for full correction and automation of each probe’s path.
Full automation is then available to allow for quick swapping of the inputs via Infiniium’s
compliance framework. For increased accuracy, purchase PrecisionProbe Advanced for
faster edge speeds and true differential measurements.
PrecisionProbe technology:
–– Properly creates custom probe
transfer function = VOut/VIn
–– Properly characterizes probed system
transfer function such that
VOut/VIn = VOut/VSrc
–– Removes unwanted S21 cable loss
Every Z-Series oscilloscope has Keysight’s
custom indium phosphide (InP) fast edge.

By characterizing and compensating for cable loss on the cable connected to the PCI
Express test fixture, the designer was able to gain between 6.5 and 13.6% margin that
would have been lost otherwise.
