MODEL 2117-8485 Up/Downconverter

1.0 General

The 2117-8485 Up/Downconverter converts 1.80 - 1.90 GHz to 8.40 - 8.50 GHz and 8.40-8.50 GHz to 1.50 -

1.60 GHz, with non-inverting spectrums. Front panel LEDs provide indication of DC Power, External 10 MHz,

and PLL Alarm. The gain is +20 dB for the upconverter and -20 dB for the downconverter. Connectors are

Type N female for the RF output and input, BNC female for the L-band input and output and external reference

input and reference output. A three-way switch controls which 10 MHz reference is being used. 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 2117 is powered by a 100-240 ± 10% VAC power supply, and in a 1 3/4” X 19” X

19” rack mount chassis.

2.0 Installation

2.1 Mechanical - The 2117-8485 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 2117-8485 can

be secured to a rack using the 4 holes on the front panel. Figure 2.0 shows how the 2117-8485 is assembled.

2.4 Installation / Operation

2.4.2 Installing and Operating the 2117-8485 Downconverter

1.) Connect -20 dBm to 0 dBm signal 8.4 to 8.5 GHz, RF1 INPUT, J102 (Figure 2.1).

2.) Connect RF1 OUT, 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, 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 10 MHz) is on (Figure 2.2).

7.) Check that a 10MHz, 0 dBm ±3 dB signal is present at the 10 MHz 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

2.4.3 Installing and Operating the 2117-8485 Upconverter

1. Connect a -40 dBm to -20 dBm signal 1.8 to 1.9 GHz, RF2 IN, J111 (Figure 2.1).

2. Connect 1.8 - 1.9 GHz to RF2 OUTPUT, J112, 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.

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 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.
