Early 7844 (SN B109999 and earlier) have issues with horizontal aberrations for sweep rates of 1 ns/Div. After discovery of the issue modification kits (040-0804-00) that replace the horizontal amplifier 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.
