Rigol DP1116A - ground loop question
« on: June 16, 2012, 04:54:44 am »
In the following video: http://youtu.be/L1M29SOLXm4?t=11m24s, the DP1116A is connected directly to an oscilloscope. I'm still learning about this stuff, but shouldn't that configuration create a ground loop? Or is 1. the DP1116A not grounded unless the grounding port is used or 2. it assumed that an isolation transformer is being used?

Thanks!

It has a floating ground output, which is not connected to earth ground.  Notice the separate green "earth" terminal.
