Early R7903 (SN B149999 and earlier) use the 670-2532-00 A11 horizontal amplifier board and have issues with horizontal aberrations for sweep rates of 1 ns/Div or faster. After discovery of the issue modification kits (040-0801-00) that replace the horizontal amplifier board were offered. For more information see the [[Media:Tek 067-0657-00 with schematics.pdf|manual]] of the [[067-0657-00|067-0657-00 Normalized Ramp Generator]] that was use to investigate this issue. | |||
