-The Type 544 is a 50MHz scope with [[tunnel diodes|tunnel diode]] triggering.
+The Type 544 is a 50MHz scope with one timebase.
-It has only one timebase.
-A factory modification, MOD 108G, was available that increased the accelerating voltage to 24kv.
+The 544 (at least the early ones) uses the same
-The 1968 catalog lists an RM544 Mod 720 which has a direct-access plug-in and has 1ns risetime.
