2016-35-140 Downconverter, 3.4 - 4.2 GHz, 140 MHz IF
The 2016-35-140 Downconverter converts 3.4 to 4.2 GHz to 140 ± 36 MHz in 125 kHz steps (1 kHz steps, option X1005) with low group
delay and flat frequency response. Synthesized local oscillators (LO) provide low phase noise and ±0.01 ppm stability frequency selection.
Push button switches select the RF frequency, gain, and other parameters. Front panel LEDs provide indication of DC power (green), PLL
alarm (red), and remote operation (yellow). Gain is adjustable manually over a +30 to +50 dB range as adjusted by the front panel multifunction push-button switches. Remote operation allows selection of frequency and gain. Parameter selection and frequency and gain
settings appear on the LCD display. Connectors are BNC (female) for IF output and the 10MHz reference input and output, and Type N
(female) for the RF input. External 10 MHz is standard. A 10 MHz output connector contains either the internal or external 10 MHz
reference signal. Unit is powered by a 100-240 ±10% VAC power supply, and housed in a 1 3/4” X 19“ X 16” rack mount chassis.
