MODEL 2015-25 Upconverter
1.0 General
1.1 Equipment Description
The 2015-25 Upconverter converts 70 ± 18 MHz to 2000 to 2500 MHz in 1.0 MHz steps (0.5 MHz steps
optional) 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 (red), Remote operation (yellow) or the
TX carrier is Muted (yellow). Variable attenuators for the IF input and output provide a gain range of -10 to +30
dB 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 for IF input, external reference input, and RF output. The 2015-25 is powered by a
100-240 ± 10% VAC power supply, and is housed in a 1 3/4” X 19” X 16” rack mount chassis.
