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 ...

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 ...

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 ...

Santa Rosa, CA. Keysight Technologies has introduced two extreme-temperature probing solutions: the N7007A extreme-temperature 400-MHz passive probe and the N7013A extreme-temperature extension kit ...

The development of fluorescent probes for imaging in Alzheimer’s disease has rapidly expanded, with these molecular tools enabling the non-invasive visualisation of pathological biomarkers such as ...

Instant synapse visualization with our fluorescence probe. A diagram showing that the fluorescent probe can visualize AMPA receptors on synapses by sprinkling. There are few scientific methods more ...
