Oscilloscopes require probes to work, and probes are not all the same. There's a wide variety with versions designed for specific tasks and applications. This ...

Passive, high-impedance probes use voltage dividers in which each element is an R-C network rather than just a resistor. When the time constants of the two networks are equal, the circuit ...

Probing solution is industry first to operate at bandwidths greater than 50 GHz with high-impedance probe head High-impedance, turnkey solution delivers bandwidths up to 52 GHz Brickwall and 40 GHz ...

Tektronix has introduced a 20 GHz differential scope probe. It costs $16,900. It is worth every penny. The P7520 was an extension of the 8 GHz P7380, but still required a huge multi-year and ...

Evaluation Engineering has a great article about scope probes from a guy at Agilent. Jae-Yong Chang gives a pretty good overview of the issues surrounding scope probes. I would add two stories of my ...

If there’s one this we electronics engineers are precious about, it’s our test gear. The instruments themselves can be obscenely expensive, since all that R&D effort needs to be paid back over a much ...

Rohde & Schwarz recently announced their MXO3 1 GHz bandwidth 12-bit oscilloscope [1], and I managed to get one to review.
