module
has
the
features
of
a
standard
module
,
plus
two
distribution
ampliers
.
Each
distribution

has
one
input
and
three
outputs

Other
Congurations
The
HP
70310A
Option
001
module
has
the
following
connections
available:
A
reference-frequency
signal,
with
a
frequency
of
5
to
300
MHz,
can
be
connected
to
the
module's
A
IN
connector
.
This
provides
three
reference-frequency
outputs:
A
1
OUT
,
A
2
OUT
,
and
A
3
OUT
.
These
outputs
will
have
the
same
frequency
as
the
reference-frequency
signal
at
A
IN.
A
reference-frequency
signal,
with
a
frequency
of
5
to
300
MHz,
can
be
connected
to
the
module's
B
IN
connector
.
This
provides
three
reference-frequency
outputs:
B
1
OUT
,
B
2
OUT
,
and
B
3
OUT
.
These
outputs
will
have
the
same
frequency
as
the
reference-frequency
signal
at
B
IN.
The
100
MHz
output
supplies
a
stable
frequency-reference
signal
for
use
by
HP
70000
Modular
Measurement
Systems
and
other
instruments
.
The
external
power
pack
can
be
connected
to
the
EXT
PWR
input
to
maintain
the
temperature
of
the
module's
internal
oven/oscillator
when
the
mainframe
is
turned
o.
The
module's
10
MHz
output
can
be
used
to
provide
a
stable
10
MHz
reference
frequency
to
another
instrument.
An
external
frequency-reference
signal
can
be
connected
to
the
module's
EXT
REF
input
connector
.
If
an
external
frequency-reference
signal
is
connected,
the
module's
internal
frequency
reference
is
automatically
switched
