There are two schemes for correcting this misalignment: | There are two schemes for correcting this misalignment: | ||
* Mechanical trace rotation: The CRT is rotated a few degrees in its mounting clamps. This only works if the CRT has an external graticule. The [[545|545A]] uses this technique. | * Mechanical trace rotation: The CRT is rotated a few degrees in its mounting clamps. This only works if the CRT has an external graticule.

* Electromagnetic trace rotation: Current is passed through a coil near CRT, creating a magnetic field that counterbalances the magnetic field in the environment. The [[647]] uses this technique. | * Electromagnetic trace rotation: Current is passed through a coil near CRT, creating a magnetic field that counterbalances the magnetic field in the environment. The [[647]] and most more recent Tek scopes uses this technique. | ||
