RE: Z channel on Tempest?

My Tek 2215a says 5v has appreciable cutoff. So I will need to invert. -----Original Message-----

Check the polarity of the z axis blanking signal. You may need to invert it.

There is a barely perceptible decrease in intensity when I hook it up but they're still visible. What's the proper way to connect for blanking?
