Re: 7704A - Delayed Sweep Intensity Too Bright

Stephen,

I'll have to check that. I think the problem is seen for other time-bases so not sure if it's a problem with the plugin but it could be.

Thanks,

Barry,

Maybe the discussion of Aux Z axis Control and Aux Z Axis Out on pages 3-16 and
3-17 of the 7B53A manual will give a clue. It describes the Z-Axis interface to
the mainframe. Since the 7B92A has a front panel contrast adjustment, the
interface probably has the ability to control intensity via a voltage level.
Perhaps a bad component in those sections of your 7B53A has that level pegged.
