When you buy a low- to mid-range oscilloscope, it usually comes standard with a high-impedance passive probe per oscilloscope channel. Compared to active probes, passive probes are more rugged and ...

When you think of a scope probe, you usually think of what is basically a wire with a spring hook and an attenuator. Those are passive probes. [Kerry Wong] shows off a pre-release active probe that ...

LeCroy's family of single-ended active probes feature a high input resistance of 1 MΩ and low input capacitance of 0.9 pF. LeCroy’s family of single-ended active probes feature a high input resistance ...

Agilent Technologies has introduced two active differentialprobes for its RF and microwave instruments. The U1818A and U1818B feature highdifferential input impedance from 100 kHz to 7 GHz and 100 kHz ...

A steady stream of advances has elevated test and measurement instruments to the point where they can reveal minute details of signals with lightning-quick rise and fall times. So, then, what about ...
