| WiFi interference on Siglent oscilloscope |

Hi all, My Powerline adaptor is getting into my oscilloscope like crazy. I can do larger measurements without too much hassle but smaller measurements are flooded by the noise. Is there a way to stop that from happening? Using a Network cable to bring the Internet to my garage is possible but a pain in the neck so I would only consider it as a last resort. Here is a video of it. Also a pic for future reference. https://share.icloud.com/photos/05frIzPO_88vhTLcRl-x_GAVQ Thank you! |

"Is there a way to stop that from happening?" powerline is known for such interferences. Just use real wireless wifi bridge. I never had such problems by using them |

indeed that was one of the options but it's not straightfoward as the room is insulated with foil and there is very little reception inside. I'll have to install something outside - or under the roof - and something with a decent speed. Any suggestions? There's no way to remove those interferences? Any wi-fi extension I've done in the years haven't worked very well though. |

The modern powerline comms use frequencies into MHz, differential mode between L and N, and, I understand, also common mode between that pair and PE. Maybe you could try a powerline filter, like this one: https://www.dem-uk.com/roxburgh/products/industrial_emc_filters/single_phase_free_standing_iec_in_line_filter_pmf/pmf6.asp Data sheet shows > 40dB insertion loss at 1MHz+. RS catalogue ref: 122-9448. For what it is, quite expensive at £52+VAT... Is there a less expensive way of doing it? 4G hotspot? We should get a few more opinions on here! |

Oh and BTW, does having the trigger set within the amplitude of the waveform make any difference ? |
