Notes :

2.

Parameter is not tested during production, but it is guaranteed by the design and qualified by means of corner lots.

4.

Parameter is measured in EWS, with limits enlarged due to tester accuracy

5.

Vertical output signals like vertical sawtooth, breathing and S-correction can only be measured via external test circuit (see

Figure 10).
