RF
CONNECTORS
The nominal
impedance
of the
following
RF
connectors
is
50
ohms.
J19
-
Auxiliary
Output
2.3
to
7
GHz
This
female, type-N
connector
nominally
provides
a
—3
dBm
RF
output
from
the YIG
oscillator.
J20
-
RF
Output
In
option
004
and
005
instruments,
this
male,
precision
3.5
mm connector
replaces
the
standard
front
panel
RF
output
connector.
Protection
from
DC
Voltages.
A
capacitor
in
series
with
the
RF
output protects
the
instrument from
DC
potentials
of
up
to
50V.

BNC
CONNECTORS
J6
-
O.SV/GHz
Maximum
Specified
Voltage.
The
output
of
this
BNC
connector
is
proportional
to
the
RF
output
frequency
(0.5V
per
GHz), across
the
entire
frequency
span.
Load
Impedance
and
Current
Limiting.
The
0.5V/GHz
accuracy
is
±1%
±2
mV
with
a
load
impedance
of
4
kQ
or
greater.
This
output
is
current
limited;
a
load of
less
than
4
kQ
causes
the
circuit
to
current
limit
at
high
frequencies.
•IV/GHz.
You
can have
an
output
voltage
ratio of
1
volt
per
GHz
by
adding
two
jumpers on
the
A28
SYTM
assembly.
This
provides
a
maximum
specified
voltage
of
19V.
Above
19
GHz,
the
output
levels
off
at approximately
20V.
J7
-
Sweep
Output
Swept Mode
Voltage
Range.
When the
instrument
sweeps,
the
voltage
range
for
this
connector
is
0
to
10V,
regardless
of
sweep
width.
CW
Mode
Voltage.
When
the
instrument
is in
CW,
the
voltage
at
J7
is
0
to
10V
across
the
frequency
range.
Manual
Mode
Voltage
Range.
In
the
manual
mode,
the
sweep
output
ranges
from
0V
at
10
MHz
to
10V
at
the
instrument's maximum
frequency,
with
proportional voltages
at
the
frequencies
between
these
two
points.
J8
—
10
MHz
Reference
Output
This
output,
from
the
instrument's internal frequency standard,
is
10
MHz
at
approximately
0
dBm.
This
signal
can
be the
master
time
base
reference
output for
a
network
of
instruments.
