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.
