Features: _x000D_ Designed for assisting automobile measurement. _x000D_ Can allow oscilloscope to measure fuel injector and primary ignition waveforms. _x000D_ Passive attenuator with 20:1 attenuation, if input a 20V signal, it can output a 1V signal. _x000D_ Because the signal is attenuated, by using this item, oscilloscope can measure voltage higher than its range(20V). _x000D_ When used in an oscilloscope to measure an inductive signal, such as a jet nozzle and a primary ignition, it provides enhanced input overload protection. Don't use it for secondary ignition tests. _x000D_ _x000D_ _x000D_ Specifications: _x000D_ Attenuation: 20:1_x000D_ Bandwidth: 10MHz_x000D_ Input Res: 1.053M _x000D_ Size: Approx. 61 x 21 x 10mm/2.4 x 0.8 x 0.4in_x000D_ Weight: 27g _x000D_ _x000D_ _x000D_ Package Included: _x000D_ 1 x HT201 Signal Attenuation
