MODEL 2017-0923#-370 Up/Downconverter

1.0 General

1.1 Equipment Description

The 2017-0923#-370 L-band Up/Downconverter has a 370 Mhz to 950-2300 MHz upconverter channel and a

950-2300 MHz to 370 MHz downconverter channel with 1 MHz step size tuning, low group delay and flat

frequency response. Multi-function switches select the frequency, gain ( upconverter 0 to +20 dB;

downconverter 0 to +20 dB), and other parameters. Front panel LEDs provide indication of DC power (green),

PLL alarm (red), remote operation (yellow). Remote operation allows selection of frequency and gain. L-Band

Frequency and Gain settings appear on the LCD display. Connectors are BNC female for the IF, optional ext 10

MHz, and the RF. 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 2017-0923#-370 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 2017-0923#-370 can be

secured to a rack using the 4 holes on the front panel. Figure 2.0 shows how the 2017-0923#-370 is assembled.
