output stage). The output voltage XCAL at the horizontal deflection plates of the CRT is measured
and horizontal calibrations are performed. During normal oscilloscope functioning the multiplexer
connects pin 3 + 4 and pin 13 + 11. This switches V7093 and V7094 on and the feedback paths for
MTB and DTB are interrupted.
The table shows the active delayed time base sections as a function of time/div setting:
