Model 2017-74 Up/Downconverter

1.0 General

1.1 Equipment Description

The 2017-74 C-band Up/Downconverter converts 70 M Hz to 6.7 - 7.025 GHz (Up) and 4.5 - 4.8 GHz to 70 MHz (Down) in 0.125 MHz steps with low group delay and flat frequency response. A common synthesized local oscillator (LO) provides frequency selection for the Up and Down converter simultaneously. Multifunction push button switches select the RF frequency, gain, and other parameters. Front pane l LEDs provide indication of DC power (green), PLL alarm for up and downconverters (red), remote operation (yellow), and Upconverter mute (yellow). Gain can be manually controlled over a 0 to +30 dB range for the upconverter and over a +30 to + 50 dB range for the downconverter as adjusted by the front panel multi-func tion 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 optional external reference input and output, and N female for RF. A high stability (±0.01ppm) option is also available. It is powered by a 100240 ± 10% VAC power supply and housed in a 1.75” X 19” X 16” 1RU chassis.

1.4 Use Information

A. 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.

B. 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.

C. Mechanical loading - Mounting of equipment in a rack should be such that a hazardous condition

does not exist due to uneven weight distribution.

D. 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.

E. 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).

F. Top Cover - There are no servicable 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 RE-INSTALLED prior to Top Cover screw replacement. FAILURE TO DO this may cause INGRESS and/or EGRESS emission problems.
