USB overload error
My labtop with power adapter pluged into 120V will not power up the Pico 3000 scope, windows is shutting down the port b/c of error message of overload to USB port. used to work but randomely, now it won't boot at all.
Re: USB overload error
Hi,
That sounds as if the laptop is having difficulty supplying enough power to the scope. When that happens the laptop will shut down the port. If it is a 320x series scope, try using the supplied external power supply. If the scope does not work on other laptops and PCs, please contact us on Help-desk to have the scope sent back for repair. It it is the laptop, we cannot help, probably the reservoir capacitors in the laptop have dried-out, reducing the peak current available.

PeterF.
