Upgraded P78 Oscilloscope Attenuator - Precise attenuation for accurate measurements The upgraded P78 attenuator provides reliable 20:1 attenuation to deliver precise readings with your oscilloscope. - Material you can trust Made from high quality PVC for durability and safe handling during electronics work. - Clear purpose and compatibility Designed to enable measurement of injector and primary ignition waveforms with an oscilloscope. - Attenuation that protects and extends your measurement range The P78 attenuator is a passive 20:1 device. By attenuating the signal, it allows the oscilloscope to measure voltages with an attenuated output around 20 V. - Simple, no-power operation with solid performance As a passive attenuator, it requires no power and preserves waveform integrity for reliable readings. - Practical use scenarios - Automotive diagnostics: capture injector pulses and primary ignition waveforms with an oscilloscope for accurate timing and voltage analysis. - Electronics lab testing: measure high-voltage pulse circuits safely by attenuating signals before the oscilloscope input. - Hobby and education: experiment with high-voltage signals while protecting the oscilloscope and learning waveform behavior.
