MODEL 2017-1727-140 Up/Downconverter

1.0 General

1.1 Equipment Description

The 2017-1727-140 L, S-band Up/Downconverter converts 140 ± 20 MHz to 0.95-1.75 GHz GHz (Up) and 2.0-

2.7 to 140 ± 20 MHz (Down) in 1 MHz steps (100 or 125 kHz steps optional). Multi-function switches select

the frequency, gain ( upconverter -10 to +30 dB; downconverter 0 to +50 dB), and other parameters. Front panel

LEDs provide indication of DC power (green), PLL alarm (red), remote operation (yellow), and Upconverter

mute (yellow). Remote operation allows selection of frequency, gain and external 10 MHz reference (option E).

Gain settings appear on the LCD display. Connectors are BNC female for the IF, RF (SMA and N optional) and

optional external reference input and output (option E). A high stability (±0.01 ppm) option (H) is also

available. It is powered by a 100-240 ±10% VAC power supply and housed in a 1.75” X 19” X 16” 1RU

chassis.

2.0 Installation

2.1 Mechanical

The 2017-1727-140 consists of one RF/Controller PCB housed in a 1 RU (1 3/4 inch high) by 16 inch deep

chassis. A switching, ± 12, +5, +24 VDC power supply provides power for the assemblies. The 2017-1727-140

can be secured to a rack using the 4 holes on the front panel. Figure 2.0 shows how the 2017-1727-140 is

assembled.
