Upgraded Version P78 Oscilloscope Attenuator Benefits and key features Precise attenuation for accurate oscilloscope measurements with an upgraded P78 attenuator. Passive 20:1 attenuation to scale higher voltage signals into the oscilloscope input safely. Specifically designed to enable injector and primary ignition waveforms to be measured with an oscilloscope. Built from PVC material for durability and reliable electrical insulation. Simple, robust solution for electronics enthusiasts seeking dependable signal attenuation. What it is and how it works The P78 attenuator is a passive 20:1 device. By attenuating the signal, it allows the oscilloscope to measure signals that would otherwise exceed its input range, up to about 20 V on the scope side. Who should use it Electronics hobbyists and professionals who need accurate measurement of highervoltage waveforms with an oscilloscope. Automotive technicians testing engine sensors, fuel injectors, and ignition systems. Typical use scenarios Automotive injector testing: use the attenuator to safely capture injector pulse signals with an oscilloscope, avoiding overloading the scope input. Primary ignition waveform capture: observe ignition coil primary waveforms without exceeding the oscilloscope's input limits. General voltage signal measurements: measure signals in electronics experiments that exceed typical oscilloscope input ranges, within the 20:1 attenuation limit. Notes Upgraded Version indicates an enhanced version of the P78 oscilloscope attenuator. Attenuation is 20:1 and the device is designed to be used with oscilloscope inputs for measuring highervoltage signals.
