MODEL 3016-2124-Downconverter

1.0 General

1.1 Equipment Description

The 3016-2124 Downconverter converts 21 to 24 GHz to 70 ± 18 MHz in 125 kHz steps (1 kHz opt -X1008).

This unit combines a multi-band block downconverter with a 3-4 GHz to 70 MHz agile downconverter to

obtain the wide tuning range. Synthesized local oscillators (LO) provide frequency selection. Multi-function

switches select the input frequency, gain, and other parameters. Front panel LEDs provide indication of DC

power, PLL alarm or Remote operation. Gain is adjustable manually (MGC) over a 0 to +30 dB range. The

frequency and gain are remotely selectable. Parameter selection and frequency and gain settings appear on the

LCD display. Connectors are 2.92 mm female for the RF, and BNC female for the IF and external 10 MHz

reference input and output. Other connector options are available. The unit is powered by a 100-240 ±10%

VAC power supply, and is contained in a 1 3/4” X 19” X 18” rack mount 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 units

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 3016-2124 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 3016-2124 can be

secured to a rack using the 4 holes on the front panel. Figure 2.1 shows how the 3016-2124 is assembled.
