Micsig Technology is aiming at mains and high-voltage GaN power supply development with a series of optical fibre isolated oscilloscope probes, with bandwidths up to 1GHz and risetimes down to ≤350ps.

Tektronix meant business when it came to APEC 2016 this week, demonstrating the IsoVu 1-GHz, 80-dB, galvanically isolated measurement probe with common-mode rejection that's up to 100,000X better than ...

InfiniiMax 4 oscilloscope probes from Keysight operate at bandwidths up to 52 GHz (brickwall response) and 40 GHz (Bessel-Thomson response). The company reports that the InfiniiMax 4 is the first high ...

Test probes go a long way toward ensuring accurate, repeatable test results. Here's a look at how both active and passive test probes are evolving to match today's broadening oscilloscope bandwidths.

[IMSAI Guy] wants you to build a non-contact scope probe. The cost? Assuming you have a bit of wire and a regular scope probe, it won’t cost you anything. Why do you want such a thing? You can see ...
