Hello Peter,

The manual (for S/N B250000-up) specifies the X-Y phase angle typically less than 3 degrees up to 50 kHz. That would be very well visible, ellipse opening (hor. or vert.) I think about 10 % of total width or height.
The signal path for the X deflection passes the horizontal amplifier. If you compare phases of CH1 and CH2 in ordinary mode then both use the same vertical amplifier. In many or most Tek 'scopes the (external) horizontal BW is very low compared to the vertical BW. For some types there is an Option for smaller X-Y phase difference.
