When I connect an oscilloscope to a function generator use both oscilloscope cable (one connect to the scope and one connect to the FG), I got 700mVpp when outputing a sine wave of 1Vpp and 10kHz.
But when I use the BNC cable connects to the FG, and the scope cable connect to the scope I got 2Vpp output with the same input.
What is the exact calculation behind this?
