The Tektronix Model 22 and successor 22A are time base plug-ins for the 555 dual-beam scope.

Type 22 is suggested as the lower beam time base, as it contains delayed trigger circuitry, and only the lower beam horizontal section is provided with delayed trigger pickup circuitry. The Delay multiplier control pot is also provided on the lower beam section.
