A
UX
VIDEO
provides
detected
video
output
(before
analog-to-digital
conversion)
proportional
to
vertical
deection
of
the

.
Output
is
from
0
V
to
1
V
.
Note
Amplitude-correction
factors
are
not
applied
to
the
video
output
signal.

accepts
the
positive
edge
of
an
external
voltage
input
to
trigger
the
receiver's
internal

A
UX
IF
is
the

signal.
This
output
is
normally
connected
to
EXT
REF
IN.

accepts
an
external

source
to
provide
the

frequency
reference
used
by
the
instrument.

LO
OUTPUT
provides
the
output
of
the
rst
LO
,
which
is
proportional
to
the
frequency
that
the
receiver
is
tuned
to
.
This
output
is
normally
terminated
with
an
attached
load.
