This item has been designed to allow fuel injector and primary ignition waveforms to be measured using Hantek oscilloscope product. Features： Can allow oscilloscope to measure fuel injector and primary ignition waveforms. Passive attenuator with 20:1 attenuation. If input a 20V signal, it can output a 1V signal. By using this item, oscilloscope can measure voltage higher than its range(*20V) Specifications： Attenuation: 20:1 Bandwidth: 10MHz Input Resistance: 1.053M Item Size: 60 * 18 * 16mm / 2.36 * 0.7 * 0.6in Item Weight: 24g /0.85oz Please note: This attenuator should not be used for any high voltage measurements other than fuel injectors and primary ignition. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
