MODEL 3016-1520-1200 Downconverter
1.0 General
1.1 Equipment Description
The 3016-1520-1200 Downconverter converts 15 to 20 GHz to 1200 ± 50 MHz in 125 kHz steps (1 kHz opt-
X1008). The 15 to 20 GHz is first converted to 7.0 GHz with an agile, high side LO and then to 1200 MHz to
obtain the wide tuning range. 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 +10 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 SMA female for the RF, and BNC female for the IF and external 10 MHz
reference input and output. Other connector options are available. It is powered by a 100-240 ±10%VAC
power supply, and is in a 1 3/4” X 19” X 18” rack mount chassis.
