Installation Procedure
CA-30RK550
Installation
Signal Combining Methods
PICO MACOM recommends connecting the headend components in the
following manner: Each of the modulators, signal processors or strip ampli-
fiers output are connected to a combining network. Either a PHC-12G or
a PHC-24G headend combiner may be used to accomplish this purpose.
It is recommended that assistance be available to safely install equipment in
equipment racks.
1. Install chassis in equipment rack (equipment rack sold separately) by
supporting the bottom and rear of CA-30RK550 at the desired eleva-
tion in rack.
The PHC-12G or PHC-24G passive headend combiner consists of two
rows of directional couplers combined by a hybrid splitter. Normally, the
odd channels are combined on one row while even channels are combined
on the other row of directional couplers for maximum isolation. The output
of the combiners may be connected to the input of a launch amplifier such
as a CA-30RK550 or CA-30RK1000. The output of the amplifier is con-
nected to the main distribution line.
2. Line up the side holes of chassis with the tapped equipment rack
holes.
3. Insert the provided screws through the mounting holes at the
extreme left and right of faceplate and thread into the tapped equip-
ment rack holes.
4. Fasten the bottom screws first, then fasten top screws. (tighten
securely).
The CHC16U/550 and CHC16U/860 sixteen channel active combiners
provides both signal combining and post amplification of the headend
signals. Up to 16 channels may be combined using the CHC16U. The
combiner gain is 15 dB per channel.
5. Connect power cord to outlet supplying line power to the amplifier.
6. Connect a cable from the output of the combining system to the IN
connector on the rear of the CA-30RK550.
A 24 channel system hook-up is shown. (The same combining result may
be accomplished by using a single PHC-24G).
7. Connect a cable from the OUT connector on the rear of the
CA-30RK550 to the input of the distribution network.
8. Using a non-metallic flat blade screwdriver adjust the gain and tilt
controls on the front panel of the amplifier to meet system design
requirements.
The two PHC-12G outputs are combined via a two-way splitter, which is
connected to a CA-30RK1000 launch amplifier. The input levels to the
combiner, whether from a modulator, signal processor or a strip amplifier,
must be at the same amplitude.
