2017-25-02 Up/Downconverter, 2.0 to 2.6 GHz
The 2017-25-01 Up/Downconverter converts 70 MHz to 2.0 to 2.6 GHz (Up) and 2.0 to 2.6 GHz to 70 MHz (Down) 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 (75) for IF and the optional external reference input and output, and BNC female
(50) for RF. A high stability (±0.01ppm) option is also available. 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.
