CHAPTER I: INTRODUCTION
1.0 Introduction:
First of all may we thank you for choosing RO.VE.R. equipment. We will do our very best to meet
your expectations, availing on the long experience gained in TV and Satellite reception systems.
The "DM3/D" receiver/demodulator was designed and developed specifically for professional
applications, combining easy–to–use functions with an agreeable design.
Each part of the receiver was designed with care to guarantee high quality operation and attractive
aesthetics. Special attention was shown to the electrical, mechanical and software designs, in order
to insure excellent operation in all working conditions.
The "DM3/D" receiver/demodulator is able to provide high quality audio/video signals, which
makes it ideal for use as a relay receiver or monitoring and control demodulator for automatic
stations.
The shielding was designed with special constructive solutions in order to guarantee a perfect
performance even in the presence of strong local electromagnetic fields.
The "DM3/D" receiver/demodulator was designed using the best electronic components available,
applying each element on the basis of its continuous use.
During the test stages, the equipment undergoes thermic cycles, mechanical vibration and
accelerated ageing. This is followed by the final test of its features.
Each piece of equipment has all its specifications checked both before and after the ageing process.
The circuit boards are arranged according to the function of each block and to simplify any up–
grading or repair.

1.1 Main Features:
The “DM3/D” has been conceived as an agile, TV stereo IF-RF receiver/demodulator, designed for
continuous use in remote premises. It was developed according to DVB ETS 300 744
specifications and is orientated towards professional applications in the broadcasting sector.
In a transmitting station, thanks to its high sensitivity, the “DM3/D” can be used as a monitoring
receiver of television programmes transmitted from other stations; the received television signal,
thanks also to the receiver’s high quality characteristics, can also be used to power the local
transmitter.
The receiver can be tuned for “channels” (see comparison table) with the possibility of storing up to
100 programmes or configurations and the channel or programme is shown on a display [24] on the
front panel.
The receiver can also function as a demodulator thanks to a 50 dB switchable attenuator at the RF
input. Furthermore the possibility of having remote control via the RS 232 socket [38] on the back
panel of the receiver/demodulator allows the control of all the circular transmitters present in a
distant receiving station.
On the front panel (see appendix), there is a LED alarm to show if the RF input level is too low and
four LEDs indicating which dual carrier audio code is being used.
The video signal reaches a PAL coder which supplies the signal in base band (CVBS: Conventional
Video Base band Signal) to three independent outputs VIDEO 1 OUT [30], VIDEO 2 OUT [36]
and VIDEO 3 OUT + TXT [35] found on the back panel.
The audio signal is available on the back panel through three simultaneous mono and stereo
balanced audio output connectors AUDIO OUT MONO [31], AUDIO OUT RIGHT 2B [26] and
AUDIO OUT LEFT 1A [27].
The “DM3/D” also has a monitoring IF output [34] on the back panel and an external I.F. loopthrough to allow signal replacement with an alternative I.F. source.
The “DM3/D” can be completely programmed, tuned, controlled and adjusted from the front panel.
The front panel keyboard can be deactivated by slide switch [20].

2.5 How to set “Configuration Save”
One of the three settings, channel mode C = CHAN, frequency mode F = FREQ, or teletext pages
P = TXT can be saved so that when the "DM3/D" is turned on it is automatically called up and
shown on the display.
To do this, press down the MEMORY/CONFIG. SAVE [23] key for 3 seconds until the words
c on appears on the display (configuration ON).
2.6 How to cancel “Configuration Save”
To cancel the CONFIGURATION SAVE function (so that the "DM3/D" starts from Prog. 01)
press down the MEMORY/ CONFIGURATION SAVE [23] key for 6 seconds until the words
coFF appear on the display (configuration OFF)
2.7 How to insert the zero carrier pulse
Keep the ZERO CARRIER [17] key pressed down to insert the zero carrier pulse (line 15) at the
video outputs. This allows you to measure the modulation depth using appropriate instruments.
Position the KEYS [20] slide switch to "OFF" to disactivate the six front panel keys.
N.B. The "DM3/D" can be connected to a PC via the RS232 socket on the rear panel [38]

CHAPTER III: “DM3/D” fault finding and diagnostics
3.0 Power Supply
When the IF audio/video demodulator is working (powered) a green led on the front panel is on
(green LED [18] on).
When the stereo audio decoder is working (powered) a green led on the front panel is on (green
LED “PWR” [12] on).
3.1 RF input signal
The “DM3/D” receiver can detect whether the signal at the RF input is OK or too low. This
situation is shown by two LED’s on the front panel (green LED “RF INPUT LEVEL OK” [3] and
red LED “RF INPUT LEVEL LOW” [4]).
You must consequently check the antenna cable connection and the correct tuning parameter
settings.
If both LED’s flash in alternation, the signal at the input is too high and should be attenuated.
On the back panel of the receiver there is a slide switch [39], for the insertion of fixed 50 dB
attenuation when the signals received are too high (>110 dBuV).
3.2 Optional board “02”: RF+Video+Teletext alarms
It is possible to insert an optional alarm board in the “DM3/D” receiver, to continuously monitor the
RF level, the video level and the presence of teletext.
If you are interested in this board please contact RO.VE.R. Laboratories or your supplier and ask
for “Option 02”.
RF ALARM
The activation of the “RF absence” alarm relay occurs when the RF level at the input connector is
insufficient to drive the AGC (red RF INPUT LEVEL LOW LED on [4]). The relay contact will
close approximately 7 seconds after the LED lights up.
The disactivation of the relay occurs when the RF level is high enough to make the AGC function
work (green RF INPUT LEVEL OK LED on [3]).
- 14 -
“DM3/D” User Manual
VIDEO ALARM
The activation of the “video level decrease” alarm relay occurs when the demodulated video level
decreases by at least 4 dB, when compared to the nominal 1 VpV. The relay is disactivated when
the video level increases until it reaches a minimum of -2 dB compared to the nominal 1 VpV.
TXT ALARM
The activation of the “teletext absence” alarm relay occurs when there is no teletext signal and it
disactivates in the presence, or return, of the teletext signal.
