Upgraded P78 Oscilloscope Attenuator Precise attenuation with an upgraded version designed for reliable, measurementready performance. Built for electronics enthusiasts who require accurate readings on the bench or in the field. Crafted from PVC material, providing a sturdy, purposebuilt tool for accurate measurements. Passive 20:1 attenuator: reduces the source signal by a factor of twenty, enabling the oscilloscope input to read highervoltage signals with reduced risk of overloading. With 20:1 attenuation, the oscilloscope input can display signals corresponding to up to about 20V at the scope, helping to protect the instrument while capturing meaningful waveforms. Function and purpose: enables you to inject and capture injector and primary ignition waveforms using an oscilloscope. 23 practical use scenarios Automotive ignition testing: measure primary ignition and injector drive waveforms with an oscilloscope, while attenuating voltage signals to safe levels for accurate analysis. Electronics bench measurements: test fastedge, highervoltage signals in power electronics or sensor circuits without overstressing the oscilloscope input. Educational demonstrations: safely illustrate voltage waveform behavior using standard oscilloscope equipment for teaching or demonstration purposes.
