TC data shows HF spikes

[teslac]

    I have an 1102 I am reading in 32 channels of TC data with.  Attached is a screen shot of a strip chart showing the data and as is evident there is narrow HF spikes in the data with a dT of 2 degrees.  I say HF only with respect to the aquisition rate of 1 Hz.  Any suggestions on how to quiet this down to 0.5 degrees of dT noise?

two options:

1- use a filter.  A median filter is known as the spike 'killer' ...

2- find the root cause. analyse the setup& grounding (ground loops?) , increase the samplerate, look for EMC noise sources (power devices: pumps, heaters, the room ligth; RF devices:, .. ) , hook up a scope,  look for correlations.
