1 SIUAION DIRECV LNB signals need amplification to a constant level for multiple distribution locations. SOLUION Model R0 provides an automatic gain controlled output that is user adjustable from - dbm to - 0 MHz. is field selected to either db or 8 db. At the minimum output setting, the LED indicators turn Green with an minimum input of - dbm. At the maximum output setting, the LED indicators turn Green with an minimum input of - dbm. RELAED CONSIDERAIONS Model R0- includes power adaptor 000A. power is directed to the 8 V input for line powering of amplifiers above. Model R0- includes power adaptor PS000A. FEAURES Ka/Ku bandwidth... 0 to 0 MHz Automatic Gain... able window & khz/diseqc passing... low insertion able Pre-Emphasis... 8 or db LED Signal Metering... Blinking Red, Green, Red APPLICAION NOES Model R0 amplifiers are spaced at () floor increments when used with model SDMSXX taps per floor. Automatic gain simplifies the design and installation knowing that the amplifier output is locked when with the signal level LED lights are Green. he model SDMSXX taps are used to couple signal from the trunk. he tap output is the tap value less than the trunk level at the point of insertion. Each tap adds insertion loss. An additional R0 amplifier is added when the tap level is too low for a SWiM multi switch.

A weather sealed F cap is shipped on the lower right F connector. With the F-cap in place, the slope pre-emphasis is db. Replacing the F-cap with a standard 7 ohm terminator changes the slope pre-emphasis to 8 db. he R0 automatic gain control window is adjustable with a variable potentiometer per channel. Signal level LEDs glow GREEN when the amplifier is operating within the automatic gain window. With potentiometers fully clockwise, the output is - dbm at the 0 MHz transponder when the input signal is greater than - dbm. With potentiometers fully counter-clockwise, the output is - dbm at the when the input signal is greater than - dbm. -0 dbm 00 feet RG - / -0 dbm - / - dbm - / - dbm SL IN IN IN IN IN IN V 0 9 SD PI-S 000A he 000A Volt, Amp power supply powers the SD PI-S, the SL LNBs, the WorldDIREC LNB and the R0 amplifier. 00 Feet RG-: SD PI-S, R0- SELECABLE : At 00 feet of RG- from the dish, we start with a negative slope of db. he R0 has a selectable slope pre-emphasis of either 8 db or db. Placing a terminator on the slope port sets the pre-emphasis to 8 db. he output signal is - at 0 MHz and - dbm at 0 MHz. In situations like a COM000 headend a flat slope is desired. ADJUSABLE PU: he R0 has an adjustable automatic gain control window. At maximum output (pot fully clockwise), the output level of the 0 transponder is - dbm. At minimum output, the window moves lower so -0 dbm at 0 MHz sets the AGC LED to GREEN and the output to - dbm.

An F-cap (shipped with each unit) is on the slope port. he R0 produces an automatic gain output of -0 dbm at 0 MHz and -8 dbm at 0 MHz. ADJUSABLE PU: he R0 at maximum output (pot fully clockwise), requires a minimum input of - dbm at 0 MHz for a GREEN LED and the output to - dbm. When the input is less than - dbm, the Level ment pots must be turned counter-clockwise until a Green LED is obtained. he 000A Volt, Amp power supply powers the SD PI-S, the SL LNBs, the WorldDIREC LNB and the R0 amplifier.

Model LAR is used as an active equalizer. It provides db of pre-emphasis. he signal out of the LAR has a negative 8 db of slope. (-7 dbm at 0 MHz & - dbm at 0 MHz) If we set the R0 at db slope pre-emphasis produces an automatic gain output of - dbm at 0 MHz and -9 dbm at 0 MHz. (At maximum output pot setting) Models LAR & R0 have energy saving regulators that conserve current from model 000A. he two amplifiers and LNBs can be powered by the single supply. he total current is 70 ma SL -0 dbm 00 feet RG - / -9 dbm - / -0 dbm 0 9 SD PI-S LAR 000A 00 Feet: LAR, SD PI-S, R0 At 00 feet the signal to the LAR- is - dbm at 0 MHz and -9 dbm at 0 MHz. he slope is 8 db.

(- dbm at 0 MHz & - dbm at 0 MHz) Set the R0 at db slope pre-emphasis. he pots are turned counter-clockwise to produce a Green AGC LED. his produces an automatic gain output of -9 dbm at 0 MHz and -0 dbm at 0 MHz. - / - dbm -9 / -0 dbm IN IN IN IN IN IN V he slope is still negative but would be fine for feeding multiple switches at the IDF as required for a COM000 system. If the signals are to be sent down a multiple floor high rise, more pre-emphasis is needed.

A 00 foot dish to amplifier distance exceeds the slope pre-emphasis of both the LAR and combined. Additional slope compensation is required. Model SEQ9 provides 9 db of additional slope pre-emphasis. We set the R0 at 8 db slope pre-emphasis. ADJUSABLE PU: he R0 at maximum output (pot fully clockwise), requires a minimum input of - dbm at 0 MHz for a GREEN LED and the output to - dbm. When the input is less than - dbm, the Level ment pots must be turned counter-clockwise until a Green LED is obtained. his produces an automatic gain output of - dbm at 0 MHz and -0 dbm at 0 MHz.

We design the trunk for 00% of the floors receiving signal. We design the IDF to be scalable to serve up to 00% of the LU with up to (8) tuners per LU. At each IDF closet we design for a minimum signal level to support multiple SWM switches. SWM switches may be cascaded to serve up to tuners. he limit is one switch in cascade.
