3272 & 3271 Series Channel Deletion Filters
This series of deletion filters attenuates the entire channel spectrum from video carrier to aural carrier to allow
reinsertion of new information without interference.
The 55 dB (typical) continuous suppression from video carrier to aural carrier has been found to be more than
ample for reinsertion.* Attenuation drops sharply at channel edges to preserve upper and lower adjacent channels.
The operating temperature for model 3271Sub-160-166 is from 0° C to 50° C. The operating temperature for
model W3272/R3272 is from 5° C to 35° C.
Note: The 3272 Series offers an extended passband to 750 MHz.
*With input signal levels lower than +12 dBm

Lowpass and Highpass Filters
The 6211LP/HP are a series of lowpass and highpass filters that are factory assembled networks, consisting of
channel deletion filters and custom designed lowpass and highpass filters. The combination results in
a “brickwall” filter eliminating blocks of channels while preserving adjacent channels of
interest. The primary applications include deleting blocks of channels for re-insertion
purposes, while maintaining the integrity of close adjacent channels. These networks allow
for maximum use of existing cable spectrum. The operating temperature for the 6211
series is from 13° C to 33° C.
