MODEL 2016-57 Downconverter

1.0 General

1.1 Equipment Description

The 2016-57 Downconverter converts 5.845 to 6.725 GHz to 70 ± 18 MHz in 125 kHz steps (1 kHz steps,

option X1005) with low group delay and flat frequency response. Synthesized local oscillators (LO) provide

frequency selection with ±0.01 ppm stability. Push button switches select the RF frequency, gain, and other

parameters. Front panel LEDs provide indication of DC power (green), PLL alarm (red), and remote operation

(yellow). Gain is adjustable manually over a +30 to +50 dB range by the front panel push-button switches.

Remote M&C allows selection of the 10 MHz reference, frequency and gain. Parameter selection and

frequency and gain settings appear on the LCD display. Connectors are BNC (female) for IF output and the

10MHz reference input and output, and Type N (female) for the RF input (other connector configurations

available). A 10 MHz output connector 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.

2.0 Installation

2.1 Mechanical

The 2016-57 consists of one RF/Controller PCB housed in a 1 RU (1 3/4 inch high) by 16 inch deep chassis. A

switching, ±12, +24, +5 VDC power supply provides power for the assemblies. The 2016-57 can be secured to

a rack using the 4 holes on the front panel. Figure 2.1 shows how the 2016-57 is assembled.
