1. Install chassis in equipment rack (equipment rack sold separately) by
supporting the bottom and rear of
tion in rack.
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).
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
connector on the rear of the CA-45RK550.
7. Connect a cable from the
CA-45RK550 to the input of the
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.

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

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.
nected to the main distribution line.
The CHC-16U/550 and CHC-16U/860 sixteen channel
provides both signal combining and post amplification of the headend
signals. Up to 16 channels may be combined using the
combiner gain is 15 dB per channel.
