Z-Active.5 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 Z0 probes.
Signal Fidelity
You can be confident in the signal fidelity of your measurements because the Z-Active architecture provides:
High bandwidth
Excellent step response
Low loading
High CMRR
Connectivity
This
family of probes uses Tip-Clip.5 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.5s solder-in probe can become Tuesday.5s handheld
tool, simply by switching tips. The Z-Active probe design allows the
probe to easily switch between solder, handheld, or fixtured
applications.
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 a probe this can add up to
significant savings in the cost of operation.
