Low voltage for output from Cyclone III starter kit

Hi FvM and UK Fixer,

Thanks for the input - i suspected a possible grounding issue between the cyclone starter kit and ext hardware so i disconnected everything and measured the output signal directly from HSMC connector on the starter kit itself.

The situation is still the same

I have an image of the waveform from my scope - i have no means of oploading or attatching it. I would gladly send it via email or messenger if you would welcome me to do so.

Its shows an almost sinusoidal wave with a frequency of 50Mhz (this is the frequency of the onboard oscillator so is correct), and p-p Voltage of 750mV.

This seems strange in itself because for the afore mentioned code, should i not expect a squarewave function at the output???

Regarding the scope - i have default parameters set, i dont think i have any option to change the sampling frequency (i beleive it is automtically set) and the impedance of the probe inputs is 1Mohm not 50ohms.

Should this have an effect?

Many thanks.
