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 ...

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 ...

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 ...

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 ...
