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 ...

For nearly 10 years, there’s been only one spacecraft able to keep its cool above the hellish landscape of Venus. The Japanese Akatsuki probe was sent to Earth’s neighboring planet to observe its ...

The Bloodhound Active Probe is an improved version of the Beagle Active Probe, and primarily mounted on key surveillance units -- the ones which are expected to have high survivability due to the ...

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 ...

Tektronix recently launched the TAP1500L, an active, single-ended probe that comes with a seven-meter probe cable. With a cable 5.7 meters longer than the original TAP1500 active single-ended probe, ...

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 ...

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 ...
