I have a HP8904A function generator. It has the option of fully differential floating output. It has 2 BNC connectors (center pin hi, center pin low, the shields are connected to earth ground)
Is it better to use a triaxial or twinaxial cable to link things to the instrument?
I.E.
Shield (Earth) (outer shield)
HI (center pin)
Low (inner shield)
vs
Shield (Earth) (outer shield)
HI twisted pair
Low twisted pair
signal to 600KHz only.
