5.1.5. Sync Separator Unit. Requires a video input of 1 V
t6 dB to provide outputs of mixed syncst line syncs, field
syncs and even field.
This unit has circuit and
performance identical to that. of UN16/546. The pcb outline
is compatible with CH1/64 bar spacing or may be trimmed to
a smaller size where required. Power requirements +12 V,
+5 V, -12 V. PCB 144 mm x 90 mm. DD(9) 1985.
5.1.5. Digit B1anker and Clamp. The unit accepts either
5.1.5. or non-S.l.S. standard video signals and produces an
output free of 5.1.5. suitable for locking colour and
monochrome monitors. Additionally the unit has a clamped
unb1anked output. It is mechanically identical to the
AM4/536 and has similar power requirements. Power
requirements +12 V, 100 mA. PCB: 4U unsupported half card.
P.l.D. Te1 1986.
