To make horizontal magnification usable, the 544 has a vernier horizontal position control in addition to the regular horizontal position control. | 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. | 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. | 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 standard 544 and standard RM544 has a total CRT accelerating voltage of 10 kV. | |||
A factory modification, MOD 108G, was available that increased the accelerating voltage to 24 kV. | A factory modification, MOD 108G, was available that increased the accelerating voltage to 24 kV. | ||
The 1968 catalog lists an RM544 Mod 720A which comes a package with a [[500-Series Direct Access Plug-in Unit|direct-access plug-in]]. The Mod 720A system has 1 ns risetime (equiv. 350 MHz). | |||
