Description
General.
The
Heterodyne
Voltmeter
Type
2006 is a
transistorized,
selective
voltmeter
for
measuring
RF
voltages
in
the
frequency
range
from
100
kHz
to
230 MHz.
It
is
provided
with
a
meter
circuit
having
a
maximum
sensitivity
of
50
pV
for
full
scale
deflection
when
switched
for
measuring
RF
voltages.
When
switched
for
modulation
measurements,
there
will
be
a
full
scale
deflection
for
80%
amplitude
modulation
(AM)
or
for
a
frequency
swing
of
± 80
kHz
frequency
modulation
respectively.
The
input
probe
has
an
impedance
of
3
M,Q
in
parallel
with
6
pF,
or
may
be
terminated
by
a 50 Q
resistor.
It
is
a
light
weight,
portable
instrument,
which
can
be
operated
from
the
mains
or
from
a
built
-
in
nickel-cadmium
storage
battery.
A
unit
for
recharg-
ing
the
battery
is
contained
in
the
instrument.
It
is
especially
useful
for
measurements
on:
Antenna
amplifiers
and
distribution
systems
for
AM,
FM
and
TV
Receivers
Transmitters
Transceivers

The
Heterodyne
Voltmeter
Type
2006
is
particularly
designed
for
measuring
the
amplitude
of
high
frequency
signals
and
determining
the
frequency
as
well
as
the
percentage
modulation.
The
measured
frequency
is
indicated
on
a
scale.
A
meter
indicates
the
amplitude
of
the
measured
RF
voltage
and
the
modulation.
A
loudspeaker
provides
an
audible
signal
check.
Input Probe.
The
miniaturized
Input
Probe
(F
ig. 1.1 )
contains
an
FET
stage
and
features
the
advantages
of
a
high
input
impedance
and
easy
handling
due
to its
small
outside
dimensions.
The
input
impedance
at
1 MHz is g
reater
than
3
Megohm
parallel
to 6
pF.
At
higher
frequencies
the
input
impedance
decreases
. At
100 MHz
it
is
about
20
kQ
and
at
200 MHz
it
is
about
5
k.Q
.
When
using
the
Attenuator
described
below
the
input
impedance
is
greater
than
10
k.Q
at
all
frequencies
up
to
200 MHz
(C
tn = 2
pF
).
A
Capacitive
Voltage
Divider
is
provided
in
order
to
extend
the
voltage
range
of
the
voltmeter.
The
attenuation
of
the
Voltage
Divider
is
60
dB
and
the
input
capacity
is
as
low
as
2
pF.
The
Voltage
Divider
is
made
as
a
mechanical
