Z-Active Probing Architecture Leads the Way
for High-speed Probing Applications
Tektronix has created a revolutionary
Z-Active probe architecture that sets the
industry benchmark for signal fidelity.
Tektronix active probe architecture preserves high bandwidth while providing
improved connectivity with low loading.
The Z-Active architecture is a hybrid
approach composed of a distributed
attenuator topology feeding an active
probe amplifier.
The Z-Active probes use a tiny passive
probe tip element that is separate from
the amplifier, extending the usable reach
of the probe. In traditional active probes,
adding this much length can introduce
signal fidelity problems. However, this
architecture maintains high DC input
resistance and presents a higher AC
impedance than previous probe architectures. It accomplishes this while providing
significant length between the probe body
and the probe attachment point to the
DUT. This architecture provides the best
of both worlds: high DC impedance like
existing active probes and the stable
high frequency loading of Z
probes.

Extended Linear Dynamic Range
Many of today’s logic signals and serial bus
signals require the capability to measure
up to several volts peak to peak. These
voltage levels may easily be viewed with
the Z-Active architecture probes (P7380A,
P7360A and P7340A) with the extended
linear dynamic range. With a 2.0 V
pk-pk
linear dynamic input range at the 5X
attenuation setting, you can accurately
measure DDR II & III, Firewire 1394b and
PCI-Express I & II signals at reduced
noise levels. In addition, the 25X attenuation setting’s linear dynamic input voltage
range can be used up to 5.0 V

for
accessing even larger signal swings
Connectivity
The Z-Active probe design allows the
probe to easily switch between soldered,
handheld or fixtured applications.
This family of probes uses Tip-Clip
™
assemblies, an interchangeable probe tip
system that enables customers to
configure their probe with the optimal tip
for their application. These detachable
assemblies make it possible to replace
a tip for a fraction of the cost formerly
associated with such hardware changes.
The several lengths and variable spacing
of the assemblies provide flexibility for
adapting to vias and other test points
of differing sizes. With Tektronix Tip-Clip
assemblies, Monday’s solder-in probe
can become Tuesday’s handheld tool,
simply by switching tips.
Value
The combination of the Z-Active architecture and the Tip-Clip assemblies
provide superior signal fidelity at a costeffective price. The inexpensive Tip-Clip
assemblies enable full performance
solder connections at a very low price
per connection. Over the life of a probe,
this can add up to significant savings
in the cost of operation.
