MODEL 4117-14 Block Up/Downconverter, Weather Resistant
*
1.0 General
1.1 Equipment Description
The 4117-14 Block Up, Downconverter converts a 0.2 - 0.4 GHz block to 1.2 - 1.4 GHz and a 1.2 - 1.4 block
to 0.2 - 0.4 GHz. Front panel LEDs provide indication of DC Power, and PLL Alarms. The maximum gain is
+30 dB for the Up and Downconverter. Connectors are Type N female for the UHF, L-band and L-band
Monitor and SMA female for the external reference input. Gain, and internal 10 MHz frequency are controlled
by the Ethernet M&C. In AUTO, the 10 MHz reference stays in external if the external level is in the +2 to +8
dBm range. The 4117-14 is powered by a 100-240 ± 10% power supply, and is mounted in a 8” W X 6” H X
16” D Weather Resistant* Enclosure.
NOTE: *Weather Resistant enclosures are designed to be water resistant for installation in an outdoor enclosure/antenna hut OR
mounted outdoors on an antenna assembly at their specified temperature ranges. They are designed to be located “out in the
elements” (water, sleet, snow, etc.) but they are not designed to be “submerged under” water. If an extended temperature range is
required, there is an Extended Temperature option (Option W21; -30˚C to +60˚C) available at an additional cost. Contact Cross for
