Analizator EU1KY

[EI8DRB]

Hi all...
A am building teh v3 AA from Yury, but I am having a strange problem. If I try to do Hardware Calib. I get a meddage saying "No Signal". Also I get this message on the Measurement and Generator screen.
If I look at the input to the SA612 at OSCI, I see a square wave about 140mV P-P, but if I look at the output at OUTA or OUTB, I see noise.

Would anyone have any ideas?
Thanks
Gerry
