Carl, thats a good point. The switching type of circuit is described / has a reference waveform in PicoScope Automotive software.

We have just uploaded the guide on testing MAF sensors to the library section of the web site.

As promised a quick guide to testing these digital MAF sensors. Testing Digital MAF sensors.pdf Any feedback would be welcome either about testing these sensors or other uses for graphing frequency. One question is whether its OK to view the signal for different MAF sensors as frequency vs time or d...

Matt, Thanks for the post and comments about the spikes. The 0 to 20kHz range is there to allow the scoping of "digital" MAF sensors but its a bit of a work in progress at the moment. The spikes are due to it being very sensitive to noise. We have this sorted in a alpha version of the software but y...

The diagnostics software requires high speed streaming of data back to the PC - this can only be done with our USB products so I am afraid that it will not work with your ADC212 (even if you use the USB adapter).

Hi,

I seem to remember this was a bug on one version of the sofware a while back. Suggest you download the latest version.

Hi,

As far as I know National Tool Warehouse is not a Pico distributor - is it a Pico 4 channel oscilloscope you are talking about, if not then this is not really the correct forum for this post.
