MODEL 2116-182193 Downconverter

1.0 General

1.1 Equipment Description -The 2116-182193 Downconverter converts 18.2 - 19.3 GHz to 0.95 -

2.05 GHz with a local oscillator at 17.25 GHz. Front panel LEDs indicate DC Power, External 10

MHz, and PLL Alarm. The gain is +25 dB. Connectors are SuperSMA female for the RF input and

BNC female for the RF output (designated L-Band), the external reference input, and the reference

output. A three-way switch controls which 10 MHz reference is being used. In the INT position, the

internal reference is used, in the EXT position, the external reference is used, and in the AUTO

position, the internal reference is used unless a +3 dBm ± 3 dB, 10MHz reference signal is connected

to the external reference input. It is powered by a 100-240 ± 10% VAC power supply, and in a 1 3/4”

X 19” X 14” rack mount chassis.

2.0 Installation

2.1 Mechanical - The 2116-182193 consists of one RF PCB housed in a 1 RU (1 3/4 inch high) by 14 inch

deep chassis. A switching, ± 12, +24, +5 VDC power supply provides power for the assemblies. The 2116-

182193 can be secured to a rack using the 4 holes on the front panel. Figure 2.0 shows how the 2116-182193 is

assembled.

2.4 Installation / Operation

2.4.1 Installing and Operating the 2116-182193 Downconverter

1.) Connect a -55 dBm to -35 dBm signal to RF INPUT, J101 (Figure 2.1).

2.) Connect the L-BAND OUTPUT, J1, to the external equipment.

3.) Connect 100-240 ±10% VAC, 47 - 63 Hz to AC connector on the back panel.

4.) Be sure DS1 (green, DC Power) is on and DS2 (red, Alarm) is off (Figure 2.2).

5.) Select either INT (for internal 10MHz ref), AUTO (for internal 10MHz ref UNLESS a external

10MHz, 0 dBm signal is connected to J2), or EXT (for external 10MHz, 0 dBm ref that is inserted

at J2) on rear panel switch S1 (Figure 2.1).

6.) If EXT is selected or AUTO is selected and there is a 10MHz, 0 dBm signal at J2, check that DS3

(yellow, Ext 10MHZ) is on (Figure 2.2).

7.) Check that a 10MHz, 0 dBm ±3 dB signal is present at the 10MHZ REF OUTPUT (J8) (Figure 2.1).

8.) AC Fuse - The fuse is a 5 mm X 20 mm, 2 amp slow blow (Type T) and is inserted in the far slot in

the drawer below the AC input as shown in Figure 2.3. There is a spare fuse in the near slot.

If a fuse continues to open, the power supply is most likely defective.

3.0 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.
