Pico Macom PLM860SAW User manual

PLM860SAW
The PLM860SAW modulator features a digital phase-locked loop (PLL) and saw
filter for superior adjacent channel performance and drift-free channel stability.
This professional grade modulator maintains a full 55dBmV output on channels
23 to 135 while accommodating HRC and IRC offset frequencies (216-860
MHz).The PLM860SAW is a very cost effective method to expand an existing
cable system beyond 300MHz.The PLM860SAW was designed to extend
channel capacity of systems using PCM55, PLM55, or PCM55SAW modulators.
Its SAW filter provides superior sideband filtering, adjacent channel compatibility,
and spurious free output. High quality modulation and RF level control poten-
tiometers assure years of reliable operation. Easy lab retuning enables inventory
savings and less down time.The PLM860SAW is shipped with all internal
adjustments preset. FCC Docket 21006 offsets are standard. Pico Macom
backs up this product with its industry leading 5-year limited warranty.
