Tektronixfor Rent, P7508 Trimode Differential Probe, 8 GHz

Product Highlights

Tektronix created the P7380A with Z-Active probe architecture and set the industry benchmark for signal fidelity. Tektronix active probe architecture preserves high bandwidth while providing improved connectivity with low loading and low noise. The Tektronix P7380A design 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 other probe architectures. It accomplishes this while providing significant length between the probe body and the probe attachment point to the DUT. Thus the P7380A provides the best of both worlds: high DC impedance like existing active probes and the stable high-frequency loading of Z0 probes.
