1 GENERAL INFORMATION
DESCRIPTION OF THE TVM450/S TVM550/S
The TVM450, TVM450S, TVM550, and TVM550S are rebroadcast-quality, phase-
locked loop (PLL)-synthesized, frequency-agile, community antenna television
(CATV) and cable system television-distribution modulators. The TVM450 models
range from 54 to 450 MHz, and the TVM550 models range from 54 to 550 MHz for
use in domestic systems.
Both modulators use an open-architecture circuit and chassis design that allows
system growth with multiple field configurations.
The TVM450/S and TVM550/S are designed to be the primary building blocks of
an intelligent CATV distribution system. At the heart of these modulators is
SCC's PLL-synthesized, dual-conversion up/down converter.
The conversion process uses SCC's high-level mixing, which eliminates out-of-band
noise floor and spurious emission problems. High-level mixing and superior design
allow the TVM450/S and TVM550/S to meet the NTC-7-recommended specifications
for a 550 MHz spectrum, without the use of external bandpass filters.
The TVM550/S and TVM550/S modulators use a unique nonvolatile microprocessor
tuning circuit. Available is an optional Composite IF Loop kit that allows the external
input of either aural, visual, or a composite IF signal through a special loop. An
alternate IF option is also available.
Channels are selected with a front panel rotary switch, and the modulators can
be set to only a legitimate output frequency. When a modulator is on line and the
frequency output is changed, a circuit mutes the RF output until the modulator
has locked onto the new output channel frequency.
Front panel potentiometers for varying video modulation, audio deviation, and
visual/aural carrier ratio have center detents. This type potentiometer allows the user to
leave the front panel controls in their center positions while properly adjusting receiver
outputs to the modulator's correct input levels. RF output is also controlled by a like
potentiometer. The user can adjust the satellite receiver, for 1.0 V p-p video and
0 dBm peak audio/Broadcast Television Standards Committee (BTSC) input levels,
without the use of expensive test equipment.
DESCRIPTION OF THE TVM550II/TVM550IIS
SCC’s superior circuit construction is carried over from previous TVM models.
These new models differ from the preceding TVM550 models in that they sport a
much-improved power supply that reduces noise and improves reliability. The
TVM550II uses the CMA60 audio demodulator, while the TVM550IIS
incorporates an SCC DSG2000BD digital stereo audio demodulator.

Control/Connector Locations
The TVM-series have convenient control locations provide ease of operation.
Front Panel for Models with CMA60 Audio Module
Refer to Figure 3-1 for the following description:
1. POWER – Red LED (TVM450) or Green LED (TVM550 models). Indicates that
the unit is plugged into the AC power and is operational.
2. VIDEO OVER MOD – Red LED. Lights when the video depth of modulation
level exceeds 87.5 percent modulation.
3. OFFSET – Green LED. Lights when the selected channel has a prepro-
grammed FCC-assigned offset frequency. The light goes out when the OFFSET
switch (27) is in the OFF or AUTO position. See rear panel callout (27) for addi-
tional switch settings.
4. RF OUTPUT – Green LED. Lights when RF output is not muted, and when
the phase-locked loop (PLL) is locked on-channel. The RF output is con-
trolled by the CHANNEL SELECT switch (6) or during a power-up condition.
When this LED is off, the RF output is muted to –75 dBc, eliminating an un-
wanted output during a tuning sequence or powering-up condition.
5. CHANNEL OUTPUT – Red, dual-digit LED numeric display. Displays the
current channel number being output to the RF OUT jack.
6. CHANNEL SELECT – Rotary switch. Rotating this switch clockwise or
counterclockwise changes the channel number sequentially higher or lower,
respectively. When rotated to a different channel, RF OUT is muted for ap-
proximately four seconds. The RF OUTPUT LED goes out during this period.
7. VIDEO MODULATION – Potentiometer. Adjusts the video modulation level.
The center detent position is preset for an 87.5 percent depth of modulation,
with a 1.0 V peak-to-peak video input signal.
8. VIDEO/AUDIO RATIO – Potentiometer. The center detent position is cali-
brated for –15 dBc aural carrier output (maintained throughout the RF
LEVEL (9) range).
9. RF LEVEL – Potentiometer. Rotating clockwise or counterclockwise in-
creases or decreases RF OUTPUT level (+45 to +60 dBmV). It is recom-
mended that these units be operated at +58 to +60 dBmV.
10. AUDIO DEVIATION – Seven-segment LED bar display. Indicates the peak
aural deviation in percent. When the sixth bar of this display is lit, a repre-
sentation of 100 percent or 25 kHz peak aural deviation is present. The sev-
enth bar represents overdeviation and should light only occasionally. The bar
display is precalibrated with an internal 15 kHz low-pass filter for accurate
monaural or BTSC (L + R) indication.

11. AUDIO DEVIATION – Potentiometer. The center detent position is cali-
brated for 25 kHz peak deviation on the aural output, with 0 dBm peak pro-
gram audio input level. Rotating this pot changes the input levels.

12. BTSC INPUT – Green LED. Lights when therearpanelAUDIO switch (17) or
4.5 MHz switch (18) are in BTSC or EXT positions, respectively.
13. VIDEO TEST – 75-ohm BNC connector. Used to monitor the video output.
14. –20 dB RF TEST – 75-ohm F connector. Used to monitor RF output. Signal
level is –20 dB.

15. MONO IN (+) and IN (–) – Screw terminals. A monaural audio input.
16. GND – Screw terminal. An external ground connection.
17. AUDIO – Slide switch. Turns pre-emphasis on or off.
18. 4.5 MHz – Slide switch. Selects either the internally generated 4.5 MHz car-
rier or an input from the EXT 4.5 MHz IN jack.
19. EXT 4.5 MHz IN – 75-ohm F connector. An input for a 4.5 MHz aural carrier
from an external source. The required input level is +30 to +60 dBmV.
20. VIDEO IN – 75 ohm F connector. An input for the video signal.
21. RF OUT – 75 ohm F connector. For the
54 to 450 MHz (TVM450) or 550 MHz (TVM550) modulator output signal.
22. REMOTE – Special connector. This jack is used when the CALT45 option is
installed.
23. VISUAL IF IN – 75 ohm F connector. For a visual IF input from other
equipment. The input level required is 40 ±1.0 dBmV.
NOTE
If an IF input is used, the frequency stability of the modulator is determined
by the frequency stability of the IF signal source.
24. VISUAL IF OUT – 75 ohm F connector. The output of the internal Visual IF
signal. Output level is 40 ±1.0 dBmV.
25. AURAL IF IN – 75 ohm F connector. An input for an external Aural IF sig-
nal. The required input level is 25 ±1.0 dBmV.
26. AURAL IF OUT – 75 ohm F connector. The output of the internal Aural IF
signal. The required output level is 25 ±1.0 dBmV.
27. OFFSET – Rotary switch. Manually selects the offset frequency. This allows
the equipment ROM to choose the FCC offset frequency automatically when
in the AUTO position, or turns the unit's ROM-pro-grammed FCC offset fre-
quency off when in the OFF position.
28. FUSE HOLDER – Houses the equipment's primary power fuse.

Refer to Figure 3-1 for the following description:
29. LEFT CHANNEL – Seven-segment LED bar display. Indicates the peak
audio deviation in percent. When the sixth bar is lit, a representation of the
rear panel left input (38), when combined with the right channel input (37),
produces 100 percent or
25 kHz peak aural deviation. The seventh bar indicates overdeviation and
should light only occasionally. The bar display is precalibrated with an inter-
nal 15 kHz low-pass filter for accurate monaural or BTSC (L + R) indication.
30. INPUT LEVEL (L) – Potentiometer. For adjusting the left channel audio in-
put level. The center detent position is calibrated for 25 kHz peak deviation
of the aural output, with 0 dBm peak program audio level. Rotating the po-
tentiometer varies input levels.
31. MONO INPUT LEVEL – Potentiometer. For adjusting the mono channel
audio input level. The center detent position is calibrated for 25 kHz peak
deviation of the aural output, with 0 dBm program audio input level. Rotating
the potentiometer varies input levels.
