Yes the inputs are voltages in automotive electronics range. I want to monitor and log the outputs of engine control unit. Some of these are 12V PWM typical frequency up to 500hz, RPM signal and analog voltages such as MAP and TPS.
For measuring automotive signals we recommend using the ADC212 (2 channels) or the PicoScope 3423 (4 channels). These are the scopes we use in our Automotive Diagnostic Kits which also include current clamps, ignition pick up leads and a whole range of probes.
