MODEL 2016-26 Downconverter
1.0 General
1.1 Equipment Description
The 2016-26 Downconverter converts 2000 to 2500 MHz to 140 ± 36 MHz in 1 MHz steps with low group
delay and flat frequency response. Synthesized local oscillators (LO) provide frequency selection. Multi-
function push button switches select the RF frequency and gain. Front panel LEDs provide indication of DC
power (green), remote operation (yellow), and PLL alarm (red). Variable attenuators for the RF input provide a
gain range of 0 to +50 dB as adjusted by the front panel multi-function pushbutton switches. Frequency and
gain settings appear on the LCD display. Connectors are BNC female for RF, IF and optional 10 MHz Input and
Output signals (
option E
). 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.
