Table 2 Cut-off and white level measurement lines; notes 1 to 3
Notes
1. The line numbers given are those of the horizontal pulse counts after the start of the vertical component of the
2. * line frequency of approximately 31 kHz.
3. (EB) is extended blanking.
Table 3 Signal input selection by the fast source switches; notes 1 to 4
Notes
1. H: logical HIGH implies that the voltage >0.9 V.
2. L: logical LOW implies that the voltage <0.4 V.
3. X = don’t care.
4. ON indicates the selected input signal.
