Signal Conditioning
Random spikes in waveform with use of 9234432
Equipment:
Windows Suraface tablet ans
9234 block with 3-axia lEPE accelerometer from PCB.
SW: LabView app.
Issue
Recently I've observe spikes entering the waveform believe its ESD relatet. But if so how can Improve the setup to avoid such spikes?
If i sit down while holding the cable (coaxial), thenstanding while holding on to the cable they appear.
Even by holding another cable crossing my sensors . Then standing up seems to make spikes.
If I charge my Surface they often apear. Also from charging with a battey to USB- -C PD output.
Once we also got disturbanse form radio com. ( offshore VHF)
Was not tuching neither the Surfac, Ni9234, cables or sensor.
But when sitting at a pipe ( totally dofferent system, 1 meter away I clearly observed noice entering my waveform.
Aslo when connecting the surface to a second screen by HDMI cable.
