MODEL 2015-58T Upconverter
1.0 General
1.1 Equipment Description
The 2015-58-T Upconverter converts 70 ±18 MHz to 5.845 to 6.725 GHz in 125 kHz steps with low group
delay and flat frequency response. Synthesized local oscillators (LO) provide low phase noise and ±1.0 ppm
stability frequency selection. Push button switches select the RF frequency, gain, and other parameters. Front
panel LEDs provide indication of DC power (green), remote operation (yellow), PLL alarm (red), or the TX
carrier is muted (yellow). Variable attenuators for the IF input and RF output provide a gain range of 0 to +20
dB as adjusted by the front panel 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 and 10MHz reference input and output, and Type N female for the RF output (other
connector configurations available). The 2015-58T is powered by a 100-240 ±10% VAC power supply; and
housed in a 1.75” X 19” X 16” rack mount chassis.
