2017-0923#-370 L Band Up/Downconverter
The 2017-0923#-370 L-band Up/Downconverter has a 370 Mhz to 950-2300 MHz upconverter channel and a 950-2300 MHz to 370 MHz downconverter channel with 1 MHz step size tuning, low group delay and flat frequency response. Multi-function switches select the frequency, gain ( upconverter 0 to +20 dB; downconverter 0 to +20 dB ), and other parameters. Front panel LEDs provide indication of DC power (green),
PLL alarm (red), remote operation (yellow). Remote operation allows selection of frequency and gain. L-Band Frequency and Gain settings appear on the LCD display. Connectors are BNC female for the IF, optional ext 10 MHz, and the RF .
A high stability (±0.01 ppm) option (H) 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.
