Model 2016-1522# Downconverter, 1.544 or 2.226 GHz to 70 ± 5 MHz

1.0 General

1.1 Equipment Description

The 2016-1522# Downconverter converts 1.544 or 2.226 GHz to 70 MHz. The gain is 0 to +50 dB, adjustable

in 1±1 dB steps. Push button switches select the input frequency, gain, and other parameters. Front panel LEDs

provide indication of DC power (green), PLL alarm (red), and Remote operation (yellow). Gain is adjustable

manually (MGC) over a 0 to 50 dB range. Remote operation allows selection of frequency and gain. Parameter

selection and frequency and gain settings appear on the LCD display. Connectors are Type N female for the IF

out and RF in and BNC female for the external 10 MHz reference input (Option E) which includes a 10 MHz

output connector which contains either the internal or external 10 MHz reference signal. The unit is powered by

a 100-240 ± 10% VAC power supply, and housed in a 1 3/4” X 19” X 16” rack mount chassis.

1.4 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 (Maximum Recommended Ambient Temperature).

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 2016-1522# 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 2016-1522# can be

secured to a rack using the 4 holes on the front panel. Figure 2.1 shows how the 2016-1522# is assembled.
