MODEL 3016-2124-Downconverter
1.0 General
1.1 Equipment Description
The 3016-2124 Downconverter converts 21 to 24 GHz to 70 ± 18 MHz in 125 kHz steps (1 kHz opt -X1008).
This unit combines a multi-band block downconverter with a 3-4 GHz to 70 MHz agile downconverter 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 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 2.92 mm female for the RF, and BNC female for the IF and external 10 MHz
reference input and output. Other connector options are available. The unit is powered by a 100-240 ±10%
VAC power supply, and is contained in a 1 3/4” X 19” X 18” rack mount chassis.
