Notes
1.
The Horizontal line frequency fH is nominally 15734.26Hz
±
0.05Hz. Interval D shall be adjusted to D = 1/(fH x 32) for the
instantaneous fH at line 21.
The clock run-in signal consists of 7.0 cycles of a 0.5034965MHz (1/D) sine wave when measured from the leading to trailing
0 IRE points. The sine wave is to be symmetrical about the 25 IRE level.
The negative going midpoints (half amplitude) of the clock run-in shall be coherent with the midpoints (half amplitude) of the
Start and Data bit transitions.
Two characters, each consisting of 7 data bits and 1 odd parity bit.
2 T Bar, measured between the 10% and 90% amplitude points.
The clock run-in maximum level shall not differ from the data bit high level by more than
±
1 IRE. The clock run-in minimum
level shall not differ from the data bit low level by more than
±
1 IRE.
