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 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™ 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 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.
