MODEL 2015-24 Upconverter
1.0 General
1.1 Equipment Description
The 2015-24 L-band Upconverter converts 140 ± 36 MHz to 950 to 2150 MHz in 1kHz, 10kHz, 100kHz, or
125kHz steps (user selectable) with low group delay and flat frequency response. Synthesized local oscillators
(LO) provide very low phase noise and ±0.01 ppm stability frequency selection. Multifunction 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
multifunction 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 Type F (female) for the RF output. SSPB +24 VDC, 2.5
Amps and 10 MHz reference can be inserted on the RF line as added options. The 10 MHz option also includes
a 10 MHz output connector, which contains either the internal or external 10 MHz reference signal. The unit is
powered by a 100-240 ±10% VAC power supply, and housed in a 1 3/4” X 19” X 16” rack mount chassis.
