MODEL 2115-122 Block Upconverter

1.0 General

1.1 Equipment Description

The 2115-122 Block Upconverter converts 0.95 - 1.45 GHz to 12.2 - 12.7 GHz with low phase noise and flat

frequency response. Frequency translation is via a 11.25 GHz local oscillator. Front panel LEDs provide

indication of DC Power, External 10 MHz, and PLL Alarm. The gain is +20 dB. Connectors are SMA female

for the RF and BNC female for the L-Band and external reference input and 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. The 2115 is powered by

a 100-240 ± 10% VAC power supply, and mounted in a 1 3/4” X 19 “ X 14” rack mount chassis.

2.0 Installation

2.1 Mechanical

The 2115-122 consists of a PCB and an RF assembly housed in a 1 RU (1 3/4 inch high) by 12 inch deep

chassis. A switching, ± 12, +24, +5 VDC power supply provides power for the assemblies. The 2115-122 can

be secured to a rack using the 4 holes on the front panel. Figure 2.0 shows how the 2115-122 is assembled.

2.4 Installation / Operation

2.4.1 Installing and Operating the 2115-122 Upconverter

1. Connect a -20 dBm to -5 dBm 0.95 to 1.45 GHz signal to L-BAND INPUT, J1 (Figure 2.1).

2. Connect the RF OUTPUT, J101, 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, +3 dBm signal is connected to J2), or EXT (for external 10MHz, +3 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, +3 dBm signal at J2, check that DS3

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

7. Check that a 10MHz, +3 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.

2.5 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.
