"Spikes" in logic channels 2205MSO

Postby MStelzl » Sun Sep 20, 2015 2:54 pm

I am a new user to the 2205MSO and Picoscope 6.
I purchased the device to analyze logic signals @ 5V amplitude.
Installation was smooth and easy.
But I have some artefacts in the signals. ( see Picture)
I played with sampling rate and threshold. But I was not able to remove the "Spikes"
Any help is welcome to improve this.

Can you post a psdata file so that we can take a look at the settings in context.

Sorry for the late reply.
I had no access to the system.
Please see the attached file.
I hope this is the information your are asking for.

That data file is fine, the data spikes are individual samples, at the opposite logic level, and do not correspond with any switching on other lines. We need some more info to try and work out what they are.

Can you tell us which of the data lines / ground line you have connected, and to where ? A picture of your setup may help.

It would be interesting to see what the analog data is of the D1 / D2 channel.
If possible can you also hook up the analog input to D1 and or D2
