MODEL 3116-7786-2150 Downconverter
1.0 General
1.1 Equipment Description -The 3116-7786-2150 Downconverter converts 7.75 - 8.65 GHz (Fc = 7.9 - 8.5
GHz) to 2150 ± 150 MHz (non-inverted) in 1 MHz steps (100 kHz, 125 kHz steps optional) with a 5.75 - 6.35
GHz local oscillator. The gain is +35 dB maximum with a 30 dB adjustment in 0.5 ±0.5 dB steps. Front panel
LEDs provide indication of Remote operation, PLL Alarm and DC Power. Frequency and
internal/external/Auto reference mode selection are controlled by front panel switches or remote selection (via
RS-232C/485, standard; Ethernet Optional) and are viewable on the LCD Display. Connectors are Type N
female for the RF and BNC female for the L-Band and external reference input and reference output. In AUTO,
the 10 MHz reference stays in external if the external level is +3 dBm, ±3 dB. The 3116 is powered by a 100-
240 ± 10% VAC power supply, and housed in a 1 3/4” X 19” X 14” rack mount chassis.
