2016-05 Downconverter, 950 - 1525 MHz, 140 MHz IF
The 2016-05 Downconverter converts 950 to 1525 MHz to 140 MHz in 1 MHz steps 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
(MGC) over a 0 to 50 dB range. The frequency and gain are 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 optional external 10 MHz
reference input and output (option E). Other connector options are available. LNB +24 VDC (option L) and 10 MHz reference (option
E) can be inserted on the RF lines. The 2016-05 is powered by a 100-240 ± 10% VAC power supply, and is contained in a 1 3/4” X 19 “
X 16” rack mount chassis.
