7. External synchronization (2:1 interlaced)
When operating the camera by external drives signals, connect sync drive signals (HD, VD) to the DC
IN
/SYNC connector, then the mode is automatically switched from the interna
sync mode.
Horizontal and vertical drive signal inputs
HD
EIA: f(H) = 15.734 kHz
CCIR: f(H) = 15.625 kHz
VD
EIA: f(V) = 59.94 Hz (f(V) = f(H)
CCIR: f(V) = 50 Hz (f(V) = f(H)
