MODEL 2116-21#-1014 Downconverter
2114 ±50 MHz to 1014 ±50 MHz (inverted) with a 3.128 GHz local oscillator
1.0 General
1.1 Equipment Description
- The 2116-21#-1014 Block Downconverter converts 2114 ±50 MHz to 1014 ±50
MHz (inverted) with a 3.128 GHz local oscillator. Front panel LEDs provide indication of DC Power, External
10 MHz, and PLL Alarm. The gain is +0 dB. Connectors are Type N female for the RF and BNC female for RF
out and external reference input and reference output. A three-way switch controls which 10 MHz reference is
being used. In the INT position, the internal reference is used, in the EXT position, the external reference is
used, and in the AUTO position, the internal reference is used unless a 3dBm ± 3dB, 10MHz signal is
connected to the external reference input. The 2116-21#-1014 is powered by a 100-240 ±10% VAC power
supply, and mounted in a 1 3/4” X 19” X 14” rack mount chassis.
