IF/1 V
Outputs
The
IF
voltages
of
channels
A
and
B
are
available
at
the
two
BNC
sockets
A
45
and B
46 on
the
rear
panel.
The
IF
is
20 kHz.
Ihe
level
and
phase
shifts
of
the
IF
outputs
correspond
to
those
of
the
RF
input
signals
in
channels
A
and
B.

SWEEP/1
V
Outputs
During
sweep
operation,
which
can
be
set
for
instance
on
the
plug-in
ZPV-E2
or
ZPV-E3,
a
voltage
corresponding
to
the
amplitude
of
channel
A
or
B
or
to
the
ratio
of
channel
B/channel
A
is
available
at
ENC
socket

SWEEP/1
V

on
the
rear
panel
in
modes
A,
B
or
E/A.
Ihe
voltage
present
at
BMC
socket
SWEEP/1
V
48
corresponds
to
the
phase
angle
between
channels
A
and
B.
These
voltages
are
produced
in a
purely
analog
way.
The
amplitude
and
frequency
autoranging
facilities
are
disabled.
When
measuring
the
ratio
B/A the
vol tage
in
channel.
A must
be
between
35
mV
and
350
mV.
This
is
monitored
by
the
microprocessor
and
any
error
is
indicated
on
the
di
splay.
