Model 2016-02-1200 Downconverter
1.0 General
1.1 Equipment Description
The 2016-02-1200 Downconverter converts 950 to 2150 MHz to 1200 MHz in 125 kHz steps with low group
delay and flat frequency response. Synthesized local oscillators (LO) provide frequency selection. Multi-
function 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 +30 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 external 10 MHz
reference input and output. External 10 MHz is standard. A 10 MHz output connector contains either the
internal or external 10 MHz reference signal whichever is selected by the user. The 2016-02-1200 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.
