MODEL 2017-93 Up/Downconverter

1.0 General

1.1 Equipment Description

The 2017-93 L-band Up/Downconverter converts 70 MHz to 950-1525 MHz (up) and 950-1525 MHz to 70

MHz (down) 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, gain, and other

parameters. Front panel LEDs provide indication of DC power (green), PLL alarm for up and downconverters

(red), remote operation (yellow), and Upconverter mute (yellow). Gain is manually controlled over a -10.0 to

+30.0 dB range for the upconverter (in 0.1 dB steps) and over a 0 to +50 dB range for the downconverter (in 1

dB steps) as adjusted by the front panel multi-function push-button switches. Remote operation allows selection

of frequency and gain. Parameter selection and frequency and gain settings appear on the LCD display.

Connectors are BNC female for IF and the 10 MHz external reference input and output, and Type F female for

RF. LNB +24 VDC (down) and SSPB +24 VDC (up) are inserted on the RF lines when the corresponding rear

panel fuse is installed. The 10 MHz reference is also inserted on the RF lines. A high stability (±0.01ppm)

option is available. Powered by a 100-240 ±10% VAC power supply and housed in a 1.75” X 19“ X 16” rack

chassis.

1.4 Environmental Use Information

A.Rack-Mounting - To mount this equipment in a rack, please refer to the installation instructions

located in the user manual furnished by the manufacturer of your equipment rack.

B. Mechanical Loading - Mounting of equipment in a rack should be such that a hazardous condition

does not exist due to uneven weight distribution.

C.Elevated Operating Ambient Temperature - If installed in a closed or multi-unit rack assembly,

the operating ambient temperature of the rack may be greater than room ambient temperature.

Therefore, consideration should be given to Tmra.

D. Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air flow

required for safe operation of the equipment is not compromised. Additional space between unit

may be required.

E. Circuit Overloading - Consideration should be given to the connection of the equipment to the supply

circuit and the effect that overloading of circuits could have on over current protection and supply wiring.

Appropriate consideration of equipment name plate rating should be used when addressing this concern.

F. Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained.

Particular attention should be given to supply connections other than direct connection to the

Branch (use of power strips).

G. Top Cover - There are no serviceable parts inside the product so, the Top Cover should not be removed.

If the Top Cover is removed the ground strap and associated screw MUST BE REINSTALLED

prior to Top Cover screw replacement. FAILURE TO DO this may cause INGRESS and/or EGRESS

emission problems.

2.0 Installation

2.1 Mechanical - The 2017 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 can

be secured to a rack using the 4 holes on the front panel. Figure 2.0 shows how the 2017 is assembled.
