the delay line is used to delay the incoming signal vertical information and synchorized it with the horizontal

delay box is a term in drag racing to describe an on board timer which is a transmission brake delay timer which forces the race car to remain stationary at the starting line.

delay line memory loops

The delay line is used to delay the incoming signal vertical information and sync it with the horizontal. Old scopes used a series of LC combinations tuned to get a good waveform representation.

The HP scope I had used a very very long coil of coax cable as the delay line and got much better waveforms than the LC delay line scopes could, but the coil of coax was bulky (about a foot long by five inches wide and 1.5 inches thick).
