Use
the
CCY
cables supplied
with
the TBC
for the
connections
between
the VTR and TBC. All the other input and output signal
connections
employ BNC
connectors.
•
Loop-through connectors
are
provided
for
Reference
COMP
VIDEO, Reference SC, Reference COMP SYNC, and so when
this
loop-through feature
is
employed,
turn
the
@, @,
@
75n
ON/OFF
switches
OFF.
In
other uses,
turn
the
switches
ON.
•
By selecting
the
@
NON COMP/COMP switch, the
@
VIDE0-3 output can be turned
into composite
video
or
non-composite video.
•
Reference
COMP VIDEO, Reference SC,
or
COMP SYNC
is
required
to gen
lock the
TBC to the external reference
signal.
Select
the
REFERENCE SELECT
switch
OQ
the
SYNC
GENERATOR 1
board
to
lock
at REFERENCE VIDEO or at
REFERENCE SYNC.
A
sufficien tly
low
time
base
error
is required for
the gen-lock
signals, and if
this
error is high,
the proper
11erformance of
the
BVT-2000
will not
be
displayed.
When
the
signal
is not
connected
to
the
reference input,
the
sync
generator inside
the
BVT-2000 automatically
becomes
the
reference.
When using
the sync generator
inside
the BVT-2000
to
generate
the reference signal, its frequency stability is
determined
by the
crystal
oscillator
on
the SYNC
GENERA
TOR
1
printed circuit
board.
For
normal
use
the
stability
is
about
30 ppm across a
temperature
range of
0°C
to
40°C. If
this
is
not
sufficient
for the
intended
operation,
replace
the crystal
oscillator
with
a
unit
having
the
required stability
or
apply
a stable reference
signal
from
an
external source.
