MODEL 2016-95 Downconverter
1.0 General
1.1 Equipment Description
The 2016-95 Downconverter converts 250 to 950 MHz to 70 ± 18 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. The 2016-95 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.
