}} | |||
The '''Tektronix Type 544''' is a 50 MHz scope [[introduced in 1964]]. | |||
It has one timebase with several horizontal magnifier modes (×2, ×5, ×10, ×20, ×50, and ×100). | |||
To make horizontal magnification usable, the 544 has a vernier horizontal position control in addition to the regular horizontal position control. | |||
The fastest calibrated sweep is 10 ns/div. | |||
Some magnification modes provide sweeps faster than 10 ns/div, but in those modes the horizontal scale is not calibrated, and a lamp on the front panel lights up to remind the operator of that. | |||
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). | |||
There is also a rackmount version, the RM544. | |||
A factory modification, MOD 108G, was available that increased the accelerating voltage to 24 kV. | |||
The 1968 catalog lists an RM544 Mod 720 which has a direct-access plug-in and has 1 ns risetime (equiv. 350 MHz). | |||
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]]. | |||
The project lead for the development of the Tektronix 544, [[546]], and [[547]] was [[Bob Rullman]]. | |||
