USB cable length

How long can the USB cable be for the 3000 series oscilloscopes? Can I use larger gauge cable to extend the length?

Thank you for your post.

The USB cable supplied is 1.8m. You can use a longer cable but it needs to be capable of providing the power to the unit. Otherwise you can use a powered hub to extend the cable whilst still keeping power to the unit.

Best Regards

Fifteen feet is the normal limit for USB but I have achieved distances of over 60 feet using a series of active repeater USB cables. It can be a bit quirky getting it started but is quite reliable once initialized. The data transfer speed is only reduced 10%.

I use this to get live data from a car in a shop and pipe it into my PC in the classroom.
