MODEL 2016-12 Downconverter
1.0 General
1.1 Equipment Description
The 2016-12 Downconverter converts 950 to 2150 MHz (in 1 kHz, 10 kHz, or 125 kHz steps - user selectable)
to 70 ± 18 MHz with low group delay and flat frequency response. Synthesized local oscillators (LO) provide
very low phase noise and ±0.01 ppm stability frequency selection. Multi-function 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 0 to +50 dB range as adjusted
by the front panel multi-function 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 RF Input, IF outputs and the 10MHz external reference input and 10MHz reference output.
The 10MHz reference signal (internal or external) can be sent to the 10MHz reference output connector and/or
to the RF IN connector. The unit is powered by a 100-240 ±10% VAC power supply, and housed in a 1.75” X
19 “ X 16” rack mount chassis.
