MODEL 2116-184 Block Downconverter
1.0 General
1.1 Equipment Description
The 2116-184 Downconverter converts 17.3 - 18.4 GHz to 0.95 - 2.05 GHz with a local oscillator at 16.35
GHz. Front panel LEDs provide indication of DC Power, External 10 MHz, and PLL Alarm. The gain is +25
dB. Connectors are SMA female for the RF and BNC female for the L-Band 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 +3 dBm ± 3 dB, 10MHz reference signal is connected to the external
reference input. The 2116 is powered by a 100-240 ±10% VAC power supply, and mounted in a 1 3/4” X 19 “
X 14” rack mount chassis.
