MODEL 1200-04 IF PROCESSOR

1.0 General

1.1 Equipment Description - The 1200-04 IF Processor consists of a transmit and receive side. The receive

side consists of one IF signal passing through an Automatic Gain Control (AGC) amplifier and then split into

three output signals each having variable attenuators to adjust their levels via front panel multi-turn

potentiometers. The AGC amplifier adjusts a -95 to -15 dBm, 50 to 90 MHz IF input signal to a -30dBm,

+5, -15 dB output. A front panel output port provides a monitor signal directly out of the AGC amplifier,

and front panel potentiometers adjust the attenuation (between 0 and 20 dB) to each of the three output

signals, DIG1RX, FDMRX, and DIG2RX.

The transmit side consists of three transmit IF signals combined into one. DIG1TX, FDMTX, and DIG2TX

signals each pass through individual attenuators controlled via front panel potentiometers and a switch that is

controlled remotely through a DB9 connector or locally with three SPDT switches located on the front panel.

A SPDT switch on the front panel selects either REMOTE or LOCAL operation. A local override feature is

included such that when the REMOTE/LOCAL switch is left in the LOCAL position, the override pin on the

DB9 can be set to override the LOCAL control and allow for REMOTE control.

DIG1 and DIG2 on both transmit and receive sides are 75in/out while FDM on both transmit and receive

sides are 50in/out. When power is removed from the 1200-04, the FDM TX and FDMRX signals pass

through to the output. IF connectors are TNC female. The 1200-04 is housed in a 1RU x 14” deep chassis

and powered by a 100-240 ±10% VAC, 47-63 HZ input power supply.

1.3 Environmental 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.

2.4 Operation

2.4.1 Installing and Operating the 1200-04

1.) Install the 1200-04 in the equipment rack.

2.) Connect to signals on the CONTROL connector, J105, as desired (Figure 2.2).

3.) Connect 100-240 ±10% VAC, 47 - 63 Hz to AC IN on the back panel (Figure 2.2).

4.) Be sure the DC (power) LED, DS6, is on (Figure 2.3).

5.) Set SW4 for REMOTE or LOCAL operation (Figure 2.3).

6.) Choose the desired TX path(s) either remotely (J105, Figure 2.2) or locally using the front-panel

switches (SW1 - SW3, Figure 2.3) and check for proper signal(s) at TX IF MON (J2, Figure 2.3) or

TX IF OUT (J104, Figure 2.2) and that the appropriate LED(s) (DS1 - DS3, Figure 2.3) is lit.

7.) Adjust attenuator pots (R1, R2, R3, T1, T2, T3) as needed. Clockwise rotation provides

increased output level (full clockwise = 0 dB atten, full counter-clockwise = 30 dB atten).

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 2.4. There is a spare fuse in the near slot. If a

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

2.4.2 AGC voltage relating to Gain - The 1200-04 IF Processor operates over a 0 to -80 dBm input range

on the RX IF side. The Automatic Gain Control (AGC) provides a constant -30 dBm +5, -15 dBm output RX

IF level over the entire input range. Pin 7 of the DB9 control connector, J105, can be monitored to determine

the approximate input level (and corresponding gain) in AGC as Table 2.2 shows.
