155-0010-00

The Tektronix M004 (P/N 155-0010-00) is a chop divider and blanking monolithic integrated circuit in a TO-99 can, designed by Les Larson.

The chop divider receives a clock signal from the chop decoder and blanking circuit and counts it down by two for the vertical switch, and by four for the plug-in chop. It also provides a horizontal chop blanking pulse if the horizontal mode switch is CHOP.
