Does a Laptop Charger Cause Signal Noise and Transmission Issues?
Hello @here how is our day going? I just observed two things just now while using my Oscilloscope and my USB to TTL converter:
When my laptop charger is connected while using the oscilloscope to measure signals, I often see noise on my readings, when i remove the charger, the noise disappers. Has anyone encountered this, and what could be the cause?
Similarly, when my laptop charger is connected and I’m using a USB-to-TTL converter, I occasionally experience data transmission hangs. Has anyone faced this issue, and what solutions worked for you?
I just started experiencing it this morning?

yeo,
i encounter this a lot
especially with my macbook
most common reason seems to be no earthing on the charger side
does your laptop come as a 3 pin or 2 pin?
Its 2 pin
so most probably its the earthing issue
I see, but i have not experienced this before with the charger before
Or probably i havent paid attention
Ok man thanks, I will get the 3 pin plug
i have a picoscope and salae logic analyzer
get noise in both of them on my macbook
so now a days, i just connect it to a 2nd laptop(one with 3 pin)
I see
Thanks man
