>Out Aglient 54622D's work the same as the Tek, i.e. if the time between the trigger point and middle of the screen stays constant, so zomming in moves the trigger position to the left or right unless it's bang on zero to start with.  It is a bit annoying as it can take an impossibly long time to move the trigger back on the screen with the hoizontal postion control if you have zoomed in considerably. Normaly you have to zoom back out, zero the trigger and then zoom back in.  Apart from that one niggle they are superb scopes though, I would love to have one at home.

This is an inherent issue with deep-memory scopes, and there is a really nice way that it could be
overcome if they thought about it-  a single button to reset the delay to zero. A 'push-to-zero'
function on the  delay time knob would be absolutely perfect for this. 
On my old 54645D, I actually made up a little external button-box to provide this function (and a
few others) by sending the appropriate RS232 command.
