which has 38V/cm vertical deflection sensitivity when operated with 24kV acceleration voltage. | which has 38V/cm vertical deflection sensitivity when operated with 24kV acceleration voltage. | ||
(Is this correct? It doesn't agree with the 5XP datasheet.} | |||
Since the vertical sensitivity at the input connector is 0.1V/cm, we can calculate that | Since the vertical sensitivity at the input connector is 0.1V/cm, we can calculate that | ||
