1.0 General
1.1 Equipment Description
The 2416-402I Downconverter has four individual channels, each one converts 950 to 2150 MHz to 70 MHz in
125 kHz steps using PLL in “exact frequency mode” with low group delay and flat frequency response.
Synthesized local oscillators (LO) provide frequency selection. Multi-function push button switches select the
input frequency, gain, and other parameters. Front panel LEDs provide indication of DC power, PLL alarm or
Remote operation. Gain is adjustable manually over a 0 to +30 dB range. The frequency and gain of each
channel are also remotely selectable. Parameter selection and frequency and gain settings appear on the LCD
display. Connectors are Type F female for the RF IN, and BNC female for the RF OUT and external 10 MHz
reference input and output. The 10 MHz reference can be inserted on all RF IN lines. The table below shows
available options. LNB +24 VDC option L1, can be inserted only on the channel 1 RF IN line. The 2416-402I
is powered by a 100-240 ±10% VAC, 47-63 Hz power supply, and is contained in a 1 3/4” X 19” X 16” rack
mount chassis.
