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.

Connectivity
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. The Z-Active
probe design allows the probe to easily
switch between solder, handheld or
Value
The combination of the Z-Active architecture and the Tip-Clip assemblies provide
superior signal fidelity at a cost-effective
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.
