MODEL 2016-03A L-band Downconverter

1.0 General

1.1 Equipment Description

The 2016-03A L-band Downconverter converts 950-1525 MHz to 70 (±18) MHz in 1 MHz steps with low

group delay and flat frequency response. The 2016-03A Input and Output levels have been optimized to support

transmit from an L-band modem to a 70 MHz IF upconverter. Multi-function push button switches select the

RF frequency, gain, and other parameters. Front panel LEDs provide indication of DC power (green), PLL

alarm (red), and remote operation (yellow). The gain is adjustable from 0 to +50 dB. Remote operation allows

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

display. Standard connectors are BNC female for IF output and the optional external reference input and

reference output, and Type F female for the RF input. LNB +24 VDC, 0.4 Amps and 10 MHz reference can be

inserted on the RF line as added options. The 10 MHz option also includes a 10 MHz output connector, which

contains either the internal or external 10 MHz reference signal. A high stability (±0.01ppm) option is also

available. The unit is powered by a 100-240 ±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.

2.0 Installation

2.1 Mechanical - The 2016-03A 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-

03A can be secured to a rack using the 4 holes on the front panel. Figure 2.1 shows how the 2016-03A is

assembled.
