Installation
BASIC INSTALLATION
1. Mount unit securely by attaching screws or bolts through mounting tabs of unit and into an equipment rack, wall
or other solid structure.
2. Attach a cable from the RF input of CA-30/1000 to the source RF signal.
3. Attach a cable from the RF output of CA-30/1000 to the distribution system output.
4. Connect unit power cord to wall receptacle or power strip supplying line power.
5. Connect a RF spectrum analyzer or signal level meter to the input test point.
6. Use the loading chart below as a guide to ensure that the input level does not exceed the suggested amplitude
level for the number of channels. If needed, reduce the input level using attenuators (FAM or PPFAM) for proper oper-
ation.
7. Connect a RF spectrum analyzer or signal level meter to the output test point.
8. Adjust the amplifier output level to match the distribution amplitude and tilt requirements.
Note: The setup procedure above and loading restrictions below assume that the RF source channels are all received
at the same amplitude level.
OPERATING GUIDELINES
Below is a chart showing the proper operation level for the CA30/1000. Please note the listed performance criteria
is for SPECIFIC numbers of channels, and must be de-rated accordingly when inserting additional channels. Also
note the amplifier's gain does not change. However, as the number of channels increases from 7 channels, the input
level (hence, the output level) must be reduced. Exceeding the input levels listed below will cause intermodulation
and picture distortions.
