MODEL 1584-29 RF Splitter
1.0 General
1.1 Equipment Description - The Model 1584-29 is two, nine way, 0.95 - 2 GHz, 0 dB gain splitters in a 1
Rack Unit chassis with redundant 100-240 ±10% VAC power supplies. Each splitter provides fused DC power
insertion on the input connector center pin, surge protection, and excellent RF characteristics. Each splitter has a
monitor connector on the front panel and eight outputs on the back panel. Two individual 90-260 VAC input power
supplies provide a diode OR’d + 22 VDC voltage for internal amplifiers and for DC to power external amplifiers
(often Low Noise Block converters or LNBs) through DC power inserters. Each LNB power line is separately
fused. A surge suppressor on each splitter input protects against high voltage transients. All splitter outputs are AC
coupled so no DC appears on their center conductors. On the front panel, green LEDs indicate presence of +22
VDC at each LNB power supply output and DC voltage test points allow monitoring this voltage with a voltmeter.
Presence of power from the +24 VDC power supplies is shown by the AC Power A and B green LEDs.
