2017-36 Up/Downconverter, 950-1525 MHz Up, 2.0-2.5 GHz Down
The 2017-36 RF Up/Downconverter converts 2.0-2.5 GHz to 70 MHz (Down) and 70 MHz to 950-1525 MHz (Up) 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 RF frequency, gain, and other parameters. Front panel LEDs provide indication of DC power (green), PLL alarm for
up and downconverters (red), remote operation (yellow), and Upconverter mute (yellow). Gain is manually controlled over a –10 to +30
dB range for the upconverter and over a 0 to +50 dB range for the downconverter as adjusted by the front panel multi-function pushbutton 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 and the optional external reference input and output, and BNC female
for RF. A high stability (±0.01ppm) option is also available. It is powered by a100-240 ±10% VAC power supply and housed in a 1.75”
X 19“ X 16” 1RU chassis.
