PICO 20:1 Attenuator (PP198)

The PP198 has been designed to allow fuel injector and primary ignition waveforms to be measured using Pico oscilloscope products.

The PP198 is a passive 20:1 attenuator. This means that a 20V signal at its input will appear as a 1V signal on the output. As the signal is attenuated, the PP198 allows voltages higher than the ±20 V input range of the Pico oscilloscope to be measured.

The PP198, when used with Pico PC oscilloscopes provides increased input protection against overloads when working with inductive signals such as injectors and primary ignition. Under no circumstances attempt to use this attenuator to measure secondary ignition (HT) waveforms, the PP178 Secondary Ignition Pickup lead should be used for this purpose.
