Horizontal Or X-Axis; Main Time Base; Delayed Time Base - Philips PM 3214 Instruction Manual

1.2.3 Horizontal or X-axis
Horizontal deflection can be obtained from either the Main time base or the Delayed time base or a combi-
nation of the two, or from the signal source selected for Xdeflection. In this case X-Y diagrams can be
displayed using A, B, the Ext. input connector, or line as a signal source for horizontal deflection.
