MODEL 2016-37-140 Downconverter

1.0 General

1.1 Equipment Description

The 2016-37-140 Downconverter converts 3.625 to 4.2 GHz to 140 ± 36 MHz in 125 kHz steps (1 kHz steps, option X1005) with low group delay and flat frequency response. Synthesized local oscillators (LO) provide frequency selection with ±0.01 ppm stability. Push button switches select the RF frequency, gain, and other parameters. Front panel LEDs provide indication of DC power (green), PLL alarm (red), and remote operation

(yellow). Gain is adjustable manually over a +30 to +50 dB range by the front panel push-button switches.

Remote M&C allows selection of the 10 MHz reference, frequency and gain. Parameter selection and frequency and gain settings appear on the LCD display. Connectors are BNC (female) for IF output and the

10MHz reference input and output, and Type N (female) for the RF input (other connector configurations available). A 10 MHz output connector contains either the internal or external 10 MHz reference signal. It is powered by a 100-240 ±10% VAC power supply, and housed in a 1 3/4” X 19“ X 16” rack mount chassis.

1.4 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 (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 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.

2.5 Menu Settings

2.5.1 Functions

This section describes operation of the front panel controls. There are three operator switches, the LCD display and alarm indicator LEDs. All functions for the equipment are controlled by these components.

The functions are (see Figure 2.5):

Power Up

Normal Display

Menu 1 Frequency in MHz

Menu 2 Gain (+30 to +50)

Menu 3 Set Unit to Remote Operation

Menu 4 Select External 10 MHz Ref

Menu 5 Set Remote mode (option Q)

Menu 6 Set RS-485 address (option Q)

Save Menu When “R” is selected in any above menu or at the end of the menu options.

Alarm indications appear on the LEDs (see figure 2.3).

All program changes must start with the operation of the Menu/Execute switch and must also end with the operation of the Menu/Execute switch verified by the “Save Settings?” Menu. If this sequence is not followed, none of the changes will take effect. If programming is initiated and no operator action takes place for approximately 30 seconds (before the final press of the Menu/Execute switch) the display will revert to its previous status and you will need to start over.

2016-37-140- Manual _Rev. A Page 13 10/05/15

2.5.2 Power On Settings

NOTE: THE LAST STATUS OF A UNIT IS RETAINED EVEN WHEN POWER IS REMOVED.

WHEN POWER IS RESTORED, THE UNIT WILL RETURN TO ITS PREVIOUS SETTINGS.

When power is first applied, the LCD display goes through three steps.

1. The LCD goes black to show all segments are functioning.

2. The software version will be displayed.

REV 1.00

3. The present frequency and gain of the downconverter is shown.

F = 3750.125

G = +30

The unit is now operational and ready for any changes the operator may desire.

2.5.3 Control Switches

1. Menu/Execute - Any change to the programming of the unit must be initiated by pressing the Menu/Execute switch and completed by pressing the Menu/Execute switch.

2. Horizontal Switch - This switch is mounted so its movement is horizontal and moves the cursor left or right.

3. Vertical Switch - This switch is mounted so its movement is vertical and has two functions: a. During frequency, gain changes, the vertical movement will raise or lower the number in the direction of the arrows.

b. For other functions such Mute on/off, the vertical switch will alternately turn the function on or off regardless of the direction operated.

2016-37-140- Manual _Rev. A Page 14 10/05/15

2.5.4 Frequency Changes

At any time during the modification process, if you have made a mistake and do not wish to save the changes you have made, do not press the Menu/Execute switch; simply do nothing for approximately 30 seconds, and the system will return to the normal operating mode or scroll to “R” and push the Menu/Execute switch and select “NO” in the “SAVE SETTINGS?” window.

To change the FREQUENCY:

Operate the Menu/Execute switch until you get to the menu item you want to change see Figure 2.5 for the sequence of menu options. The following display is for changing the downconverter frequency:

F = 3750.125

R

Pressing the Up/Down switch down will toggle the display to:

F = 3850.125

R

By using the horizontal rocker switch the cursor can be moved left or right .

F = 3850.125

R

NOTE: CHANGES DO NOT TAKE PLACE ON FREQUENCY UNTIL YOU GO TO THE SAVE

MENU AND INDICATE YOU WANT TO SAVE THE CHANGES.

When the display indicates the value desired you can push the Menu/Execute switch to get to the next item:

G = +30 R

OR you can scroll to “R”, push the Menu/Execute switch to get to:

SAVE SETTINGS?

Y N

Selecting Y will save the new settings. Selecting N will revert to the previous settings.

Pushing the Menu/Execute switch then takes you to this:
