trace looks like wide paint brush?

Postby hansimports » Tue Oct 18, 2011 2:05 am

I am a first time user with this pico scope.
Not sure if my problem is hardware, software or me??
No matter what setting i select, the traceline (O2 sensor) looks like it has been done with a super wide paintbrush.
Any suggestion would be appreciated.

Hi Hans,

Hard to say without seeing the data file, but most likely you have sample rate too high for the O2 sensor. Turn it down, or apply some low pass filter. What version of PicoScope are you using? Found under Help/About.
