The 2483-40311 Translator has four individual channels, each one converts 220 to 380 MHz (300 ± 80 MHz) to 970 to 1130 MHz
with low group delay and flat frequency response. Synthesized local oscillators (LO) provide frequency selection. Push button
switches select the gain and other parameters. Front panel LEDs provide indication of DC power, PLL alarm and Remote operation.
Gain is adjustable manually over a 0 to +20 dB range in 0.5 ± 0.5 dB steps. The gain of each channel is also remotely selectable.
