Fancy measurement gear is often expensive to buy, but some bits of kit are entirely DIY’able if you’re willing ... away around 500 MHz. El-cheapo probes aren’t going to cut it here.

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.

This is the first 90-degree foldable circuit probe tester in the world. Designed with both professionals and DIY enthusiasts in mind, this latest addition combines advanced features with practical ...

The 1GHz scopes are available in DSO and MSO formats and with two or four channels. Agilent has also added a three digit voltmeter and a five digit counter, both using regular oscilloscope probes.

Optional A3000 Series high-impedance active probes are available, with an input capacitance of 0.9pF in parallel with 1MΩ, and the ability to pass through the full 750MHz or 1GHz to the probe tip.
