Recently, an EDN reader asked “Why do oscilloscope manufacturers put amplifiers on their probe tips rather than in the oscilloscope?” Placing the amplifier in the probe minimizes signal losses in the ...

The oscilloscope is probably the most versatile piece of test equipment you can have on your electronics bench, offering a multitude of possibilities for measuring timing, frequency and voltage as ...

A differential probe, a device for measuring the voltage between two points in a circuit rather than the voltage between a point and ground, it an extremely useful addition to any electronics bench.

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.

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.

Tektronix has announced a second-generation of IsoVu isolated oscilloscope probes, claiming smaller size, easier use and enhanced electrical performance. Isolated probes are for probing power systems ...

—WaveLink ST Probe Module, and TF-DSQ Probe Calibration and Deskew Fixture Create Best Solution for Preserving True Shape and Timing of High-speed Signals— Chestnut Ridge, NY—LeCroy Corporation ...

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 ...
