There
are
two
reference
ports
on
the
M9347A.
One
port
is
“Clock
In”
and
the
other
is
“Ref
In.”
They
serve
similar
purposes
but
have
different
inputs.
“Ref
In”
is
for
a
100
MHz
reference
signal
at
+10
to
+14
dBm.
“Clock
In”
is
designed
for
4.8
GHz
and
19.2
GHz
at
-6
to
0
dBm.
Click
“Run
Clock
Alignment…”
After
the
alignment
has
been
completed,
your
M9347
A
is
ready
to
use.
A
clock
alignment
must
be
completed
if
you
decide
to
switch
the
clock
signals.
Do not change any DDS settings before the clock alignment, as
this could produce inaccurate signals.

Getting
Started
Guide
The M9347A-H02 module needs a 100 MHz clock signal to align
both of its DDS outputs. This can be supplied through the 100 MHz
Reference In port for single module configurations, or through the
M9800-61601 custom mini-HDMI cable for multi-module
configurations.
A 100 MHz
r
eference can also be supplied
with
an M9300A

Once you have connected a 100 MHz signal to “Ref In”, or a 4.8 or 19.2 GHz signal
to “Clock In”, select the correct signal in the Clock Source
drop-down
menu.
