1.0 General
1.1 Equipment Description
The 2416-402 Downconverter has four individual channels, each one converts 950 to 2150 MHz to 70 MHz in
125 kHz steps using PLL in “fractional frequency mode”(NOTE 1) with low group delay and flat frequency
response. Synthesized local oscillators (LO) (NOTE 1) 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, and BNC female for the IF and external
10 MHz reference input and output. The table below shows available options. LNB +24 VDC (option L1, on
channel 1 only) and 10 MHz reference can be inserted on the RF lines. The 2416-402 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.
