The cable’s capacitance adds to the scope’s input capacitance and shunts the scope’s 1-M? input resistance, resulting in a time constant of approximately 100 µs. Such a severe low-pass filter begins ...

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 ...

Saelig Company, Inc. announces the availability of the Saker-MV ISOVP Probe—a novel voltage probe that enables high voltage isolated measurements via fiber optic cables. Optical fiber isolation ...
