Good point - didn't read that properly! I'm just using straight BNC -
2x croc clip on all three inputs. No probes.

I'm using a Tektronix 475 Oscilloscope and, of course, I use XY mode for testing to see if the X and Y signals look good on the screen. There is an external Z axis channel in the back, but I've never gotten it completely to work. Someone once told me that I need to use an inverter to invert the signal into the probe - which sort of works, but I still see the vector retrace lines.
What do you mean "into the probe"? If you're using a X10 probe after the inverter there wouldn't be enough signal left for proper blanking.
Is it possible to completely blank out the Z signals so that the picture looks the way it's supposed to?
Thanks
