The 5B42 uses several Tek-made ICs − two [[155-0109-01]] trigger circuits, a [[155-0049-00|155-0049-xx]] sweep control, and two [[155-0042-03]] or [[155-0028-00]] Miller integrators.
The 5B42 uses several Tek-made ICs, a [[155-0049-00|155-0049-xx]] sweep control circuit, and two [[155-0042-03]] or [[155-0028-00]] Miller integrators.
Before S/N B060000, the trigger generators were implemented using a number of 10k ECL gates.  From S/N B060000 onward, these were replaced by a pair of [[155-0109-01]] trigger circuits.
