Siglent SDS804X HD - No USB Power From Scope ? *Got Power But Trips Port*

Yes - every troubleshooting task is an opportunity to expand the lab lol ;-)

I've already ordered a FNIRSI usb meter - I've been wanting one for a while but other gear was always prioritized...

More pixels = more betterer  :-DD

But the biggest thing is that I believe this tester allows for a separate pc monitoring connection outside of the source and supply ports.  I'll need something like this because as soon as I test the probe it's going to trip the USB port on the scope, which would otherwise shut down the meter as well, rendering the test useless.

I'll probably end up getting a current probe as well - still leaning towards the Hantek CC65 given it's price & features.  Reviews show this probe has a bit of a drifting issue, but given my infrequent need it's probably the best bang for the buck.

Has anyone ever tried using the shunt inside a multimeter?  Like if I use the meter inline on the ma setting and then use the scope to probe both sides of the meter jacks?  I could perhaps use 2 scope channels with math difference between the two if I test the positive rail, or perhaps if I shunt the negative rail (which should be scope ground) then I could use a single channel on the DUT side of the meter shunt?  Obviously cannot connect channel ground to any portion of the positive rail ;-)

I'll have to poke around to see if any meters spec their shunt resistances...
