The PFAM550 is a professional re-broadcast grade frequency agile double
heterodyne conversion audio/video modulator. Its SAW filter provides superior
sideband filtering, adjacent channel compatibility and spurious free output.
The PFAM550 provides 57±2 dBmV output over 82 channels from CATV
channel 2 to 78 accommodating HRC and IRC offset frequencies. The unit
features a composite audio-video IF loop, which provides compatibility with
encoders, ghost cancellers, and video-override applications. Front panel
DIP-switch controlled phase-locked-loop (PLL) allows easy channel selection
and drift-free channel stability. High quality modulation and RF level control
potentiometers assure years of reliable operation. The modulator is shipped
with all internal adjustments pre set, and FCC Docket 21006 offsets are
standard. Pico Macom backs up this product with its industry leading 5-year
limited warranty.
