MODEL 2005-10 Test Upconverter
1.0 General
1.1 Equipment Description
The 2005-10 Test Upconverter converts a 70 MHz or 140 MHz IF signal to 2000 to 2500 MHz in 1 MHz steps
with selection of high side LO (C = inverted) or low side LO (Ku = non-inverted) and 70 or 140 MHz input
over the 2.0 - 2.5 GHz range.
Featuring low phase noise, these units are used to loop 70 or 140 MHz modulators to 2.0 - 2.5 GHz receivers
for test purposes. The 70 or 140 MHz carrier input is mixed with a synthesized local oscillator (LO) signal.
The output frequency is selected with four BCD switches which control the synthesized LO. Front panel
LEDs light when DC power is applied (green) and when a PLL alarm occurs (red). The mixer output is
applied to the output attenuator providing a nominal gain of -10 dB (high gain) or -30 dB (low gain).
Connectors are 50ΩBNC (female) for the IF input and for the RF output (other connector options are
available). Wall power supply options are -P for 120 VAC, 60Hz, and -P4 is 100-240 ±10% VAC.
The 2005 can be mounted on a 1 3/4” X 19 “ rack mount panel (option -R).

2.0 Installation
2.1 Mechanical
The 2005 is packaged in an aluminum extrusion. The -R option is mounted on a 1 3/4” X 19” panel that can
be mounted to a rack using the 4 holes at the ends. The unit derives +DC from the RF out center conductor
(+14 to +24 VDC) or the wall power supply (+15V unregulated, option -P, -P4). See Figure 2.3.
2.1.1 Cleaning Instructions

2.4 Accessing the PC Card
There are NO USER JUMPERS or other on-card controls. ALTHOUGH IT IS NOT RECOMMENDED AND
MAY VOID THE WARRANTY the following shows how to remove the printed circuit board (PCB) from the
extrusion:
1. ALWAYS REMOVE POWER when installing or removing the PCB from the extrusion
2. Remove four (4) rear panel screws (see Figure 2.3).
3. GENTLY pull the rear panel and PCB assembly completely out of the extrusion.
4. To install the PCB, GENTLY push the rear panel and PCB assembly completely into the extrusion
Make sure the shield goes in the lower channel and the PCB in the next channel above that in the
extrusion and that the front panel controls go through the front panel holes.
5. Install four (4) rear panel screws.

2.5 Installation / Operation
2.5.1 Installing and Operating the 2005-10
1. If using the receiver LNB voltage to power the 2005-10, be sure +14 to +24 VDC is on the RF
center conductor. If using the wall power supply (options -P or -P4), connect the power supply to
the DC POWER connector and either 120 VAC (-P) or 100-240 ±10% VAC (-P4) (Figure 2.2)
2. Select either C or KU band (SW6) and either 70 or 140 MHz IF (SW5) using the front panel
switches (Figure 2.1).
3. Select either HI or LOW GAIN using the switch (SW7) on the rear panel (Figure 2.2).
4. Connect a -10dBm max (LOW GAIN) or -25 dBm max (HI GAIN) signal to IF In, J1 (Figure 2.2).
5. Connect the RF OUT, J2, to the receiver under test (Figure 2.2).
6. Set BCD switches, SW1 to SW4, to the desired frequency (Figure 2.1).
7. Be sure DS1 (green, DC Power) is on and DS2 (red, Alarm) is off (Figure 2.1).

2.6 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 eqipment 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 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.
