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 | |||

The 544 (at least the early ones) uses the same [[tunnel diodes|tunnel diode]] triggering circuit | |||
as is used in early [[547]] (tunnel diode in the collector load of a PNP differential amplifier). | |||
A factory modification, MOD 108G, was available that increased the accelerating voltage to 24kv. | |||
The 1968 catalog lists an RM544 Mod 720 which has a direct-access plug-in and has 1ns risetime. | |||
The | |||
The vertical amplifier and low voltage power supply of the 544 are the same as those of the [[546]] and [[547]]. | |||
The 544 uses the [[154-0478-00]] CRT which is also used by the [[543|543B]], [[545|545B]], [[546]], and [[547]]. | |||
