+The Type 544 is a 50 MHz scope [[introduced in 1964]].  It has one timebase.
+The timebase has several horizontal magnifier modes: x2, x5, x10, x20, x50, and x100.
+To make horizontal magnification usable, the 544 has a vernier horizontal position control in addition to the
 regular horizontal position control.
