A sufficiently low time base error is required for the

n-lock

and if this error is high, the proper

of

BVT-2000 will n

When the
sig
nal is
no
t conn
ec
ted to the reference input,
the
sync

nera
tor
inside the BVT-2000 au
tomat
ically becomes the
reference.
When using the sync generator inside the BVT-2000
to
generate
the reference signal, its frequency stabili
ty
is determined by the
crystal oscillator
on
the
SYNC GENERA TOR 1 printed circuit
board. For normal use the stab
il
ity
is
about
30 ppm across a
temperature range
of
0°C
to
40
°
C.
If
this is n
ot
suffici
en
t for the
intended operation, replace the crystal oscillator with a
unit
having
th
e required stab
ili
ty
or app
ly
a stable reference signal
from an external source.
