Model 2017-74 Up/Downconverter
1.0 General
1.1 Equipment Description
The 2017-74 C-band Up/Downconverter converts 70 MHz to 6.7 - 7.025 GHz (Up) and 4.5 - 4.8 GHz to 70
MHz (Down) in 0.125 MHz steps with low group delay and flat frequency response. A common synthesized
local oscillator (LO) provides frequency selection for the Up and Down converter simultaneously. 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 can be manually controlled over a 0 to +30 dB range for the upconverter and
over a +30 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 for IF and the optional external reference input
and output, and N female for RF. A high stability (±0.01ppm) option is also available. It is powered by a 100-
240 ± 10% VAC power supply and housed in a 1.75” X 19” X 16” 1RU chassis.
