2017-25 Up/Downconverter, 2.0 - 2.5 GHz
The 2017-25 Up/Downconverter converts 70 MHz to 2000-2500 MHz (Up) and 2000-2500 MHz to 70 MHz (Down) in 1 MHz steps (500
kHz, option -5) with low group delay and flat frequency response. Synthesized local oscillators (LO) provide frequency selection. Multifunction 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 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 (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.
