Hi James Physically I have connected the signal generator to the katadc's "i" input connector with a square wave at 50MHz with amplitude of 2Vpp.
The simulink model is connected as follows: [image: Inline image 2] If I program the ROACH and pull a spectrum of It I get nothing (only a straight line through zero) or sometimes I get the most random noise that is all over the place.
