ABSTRACT:
A scanning velocity modulation deflection signal generator comprises a variable conduction device coupled to said scanning velocity modulation deflection signal generator. In a first condition the variable conduction device provides a feedback path to control a scanning velocity modulation deflection signal, and in a second condition the variable conduction device interrupts the feedback path and inhibits generation of the scanning velocity modulation deflection signal.
