Description

The PFAM-550SUB is a frequency agile double hetero- dyne conversion audio/video modulator. Its superior sideband filtering provides adjacent channel compat- ibility and FCC Docket 21006 frequency accuracy. The PFAM-550SUB provides 57 ±3 dB output from sub- band channel T7 through cable channel 78 including HRC and IRC off-set frequencies. The channelization

can be changed by resetting the DIP switches accessed through the front panel. High quality external modu- lation and RF level controls assure years of reliable operation. The modulator is shipped with all internal adjustments pre-set, and FCC Docket 21006 off- sets are standard at no extra cost. Pico Macom Inc. backs the product with a five year limited warranty. *
