1.0 General
1.1 Equipment Description
The 2415-402 Upconverter has four individual channels, each one converts 70 MHz to 950 to 2150 MHz in 125
kHz steps with low group delay and flat frequency response. Synthesized local oscillators (LO) provide
frequency selection. Push button switches select the output frequency, gain, and other parameters. Front panel
LEDs provide indication of DC power, PLL alarm or Remote operation. Gain is adjustable manually over a 0 to
+30 dB range in 0.5 ± 0.5 dB steps. The frequency and gain of each channel are also remotely selectable.
Parameter selection and frequency and gain settings appear on the LCD display. Connectors are Type F female
for the RF, and BNC female for the IF andexternal 10 MHz reference input and output. The10 MHz reference
can be inserted on all RF lines. The table below shows available options. SSPB +24 VDC option V1, can be
inserted only on the channel 1 RF line. The 2415-402 is powered by a 100-240 ±10% VAC, 47-63 Hz power
supply, and is contained in a 1 3/4” X 19” X 16” rack mount chassis.
