Modcl884
The
Model
884
FM
Modulation
and
Stereo Monitor
contains
a
low
level
RF preselector,
FM
monitor, stereo
baseband
monitor,
and
a peak detector. Four major circuit boards per•
form
these
functions:
RF
Preselector A
1,
FM
Demodulator
A3,
FM
Stereo
A4,
and
Display
Driver
A6.
The
block
diagram,
Figure
6•
l,
is
located
in
Section
6of
this
manual.
RF input
from
either transmitter
or
antenna enters the
884
rear panel
and
is
routed
to
RF
Preselector A
1.
Here
the
signal
is
padded through
the
attenuated circuit to a balanced
mixer.
The
900
kHz
IF
signal
is
sent to a
low
pass
filter.
This
IF
is
then routed to the
Demodulator
Board
A3.
.
FM
Demodulator
A3
receives
the
900
kHz
IF,
demodulates
the
signal,
and
delivers a pulsed
output
that
is
filtered
and
amplified.
The resulting
signal
is
filtered
and
routed to
the
FM
Stereo
Board.
On
A4
the
composite
signal
is
filtered
and
returned
to
A3
and
to
the
front
panel
monitors
and
test
outputs.
Separation adjust
is
also
performed
on
A4.
Positive
and
negative
modulation
are
used
to
drive
the
front
panel
PEAK
flashers
on
A6,
the
Display
Driver.
Each
modulation
peak
is
compared
in
a
peak
detector
to
a
voltage
olr
tained
from
a
constant
current
source
by
means
of
resistances
selected
by
pushbutton
switches
on
the
·
PEAK
MODULATION
flashers.
The
pulse
outputs produced
by
the
peak
detect0rs
when
modulation
exceeds
user
preset values are
applied
to
the
front
panel LED
flashers,
which
light
for
approximately
2 seconds..

(Figure

The RF input
to
the
monitor
comes
from
the
sampling
point of the transmitter
as
a high;
level
signal
or
from
an
antenna. The
high
input
level
enters
the
884
through the rear panel
RF INPUT HI

connector
J7.
The
signal
is
fed
through the adjustable
at•
tenuator
HI

SET
R2
on
the rear
panel.
This
high
level
input
signal
is
adjusted
for
a
constant

and
goes
to
the
AM

detector,
which
is
routed
to
the

also
lights
the

STEAM POWERED RADIO.COM
Model 884
When an antenna signal is fed to the ANfENNA INPUT, JS, it is routed to Zl and mixed
with the frequency synthesizer L.O. (local oscillator) and becomes a 10 .7 MHz IF. This IF
is fed to linear phase filter FLl and then the lF amplifier Ul. At Ul, the level detectors
detect the antenna
level as the de component. When detected, the antenna level is fed to
US, the mute detector. The factory sets the mute level for 40 µY RF input. When the mute
level is less than the factory •set level, US shuts off the demodulator. This level also goes to
the rear panel terminal strip, TB 2.
The IF from Ul is also fed to Tl, the IF transformer, and then to U17, the balanced mixer .
The 10 .7 MHz signal mixes with the second LO., 10 MHz, from the timebase crystal oscil-
lator. The mixed signal goes to the low pass filter which looks for the 700 kHz second IF.
This 700 kHz is routed to the Q7 and Q8 switch and fed to A3, the FM Demodulator Board.
The 10 MHz timebase is crystal-controlled oscillator Yl and its associated components. It is
the reference for the PLL frequency synthesizer and is also the second LO .
4.3 FM Demodulator A3 (Figure 6-5)
The 900 kHz IF signal which is applied to the FM Demodulator Board A3 through a relay
to a pulse counting FM demodulator circuit. The limiting amplifier, Ul, is driven into
saturation
to provide limiti ng. U2 is a one -shot multivibrator acting as a pulse averaging dis-
criminator. It delivers a pulsed output whose frequency is the same as the IF but with a
fixed pulse width. The duty cycle in the output pulse train varies with the modulation and
the audio is recovered by passing the discriminator output through a low pass filter. Transis-
tors Ql thru Q4 make up the clamping circuit.
The
low pass filter consists of 1.2 and L3 and amplifier U7. This ci rcuit provides a flat
response to 100 kHz and linear phase in order to give good stereo measurements. The fre•
quency response rolls off after 100 kHz to eliminate any resiual 900 kHz. Amplifier UlO
raises the audio level to 1 Vrms.
The monitor calibration circuit consists of U3 thru U6. The 358 kHz output of the timebase
is divided down to 4.48 kHz, which is then used to gate the 200 kHz on and off at a 4.48 kHz
rate. This simulates a 100% modulated input. When the front panel METER CAL switch
is depressed, this calibration si gnal is fed into limiting amplifier Ul and discriminator U2 in
place of the 900 kHz IF. After passing through a 7.5 kHz calibration low pass filter, it is
amplified by U8, which is adjusted by CAL LEVEL ADJUST R29 to give a 100% reading
on the TOTAL MODULATION/fEST meter. The signal can also be used to check meter
and flasher calibration. The circuit is very stable and can be · used to correct drifts in the
one -shot discrimin ator U2 and the meter amplifiers.
