The CTA-30/1000’s Tilt Adjust control should be used to set the appropriate slope per system
specifications. Note that the Tilt Adjust allows the adjustment of the gain-to-frequency
characteristic of the amplifier.
When making adjustments always apply the following principles:
3
Input signal levels should ALWAYS exceed the noise figure of the amplifier by 3 to 6
dB.

The primary purpose of tilt (equalization) in a cable TV plant is to compensate for the
slope generated in coaxial cable between the high and low TV frequencies. When
various TV channels, with respect to frequency, are transmitted through coaxial
cable they are subjected to increasing attenuation (loss). Simply put, as the
frequencies of the TV carriers are increased, attenuation loss (dB) increases. A
variable tilt control is installed in this amplifier to compensate for this slope in cable
resulting in a flat frequency response at the output
8. TROUBLESHOOTING
a. Ensure you are using quality multiple shielded cables with quality radial or
compression F-connectors.
b. Ensure the F-connector’s center conductor is making solid contact with the CTA-
30/1000’s Input and Output ports, and the appropriate RF source and RF distribution
network connectors.
c. When taking measurements it is always best to use an RF spectrum analyzer or
quality signal level meter. Initially, level measurements should be taken from the
CTA-30/1000’s Output port. However, for testing while the amplifier is in service use
the Input Test and Output Test ports for setup and field maintenance. Note that each
Test port is padded down –20 dB and the 20 dB must be added back in when
determining level settings and output.
