MODEL 2016-0510 Downconverter
1.0 General
1.1 Equipment Description
The 2016-0510 Downconverter converts 500 to 1000 MHz to 70 ± 18 MHz in 1 MHz steps (125 kHz to 1 kHz step options available). Synthesized local oscillators (LO) provide frequency selection. Push button switches select the input 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 (MGC) over a 0 to 50 dB range. Remote operation allows selection of frequency and gain. Parameter selection and frequency and gain settings appear on the LCD display. Connectors are BNC female for IF and the optional external reference input and output, and Type F female for the RF input. The external 10 MHz option E includes a 10 MHz output connector which contains either the internal or external 10 MHz reference signal. A high stability Option H
(±0.01 ppm) is also available. The unit is powered by a 100-240 ± 10% VAC power supply, and housed in a
1 3/4” X 19” X 16” rack mount chassis.

2.4 Operation
2.4.1 Installing and Operating the 2016-0510 Downconverter
1. Connect a -70 dBm to -20 dBm signal to RF IN, J2 (Figure 2.2)
2. Connect the IF OUT, J1, to the external equipment
3. Connect 100-240 ±10% VAC, 47 - 63 Hz, 25 watts max. to AC on the back panel.
4. Set the input frequency (See Section 2.5 Menu Settings).
5. Set the gain for 0.0 to +50.0 dB (See Section 2.5 Menu Settings).
6. Be sure DS6 (green, DC Power) is on and DS3 (red, Alarm) is off (Figure 2.3).
7. 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.

2.5 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 (0 to +50, 1 dB steps)
Menu 3 Set Unit to Remote Operation
Menu 4 Select External 10 MHz Reference (Option -E)
Menu 5 Set Remote mode (Option -Q)
Menu 6 Set RS-485 address (Option -Q)
Save Menu When go to end
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 12 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.
2016-0510 Manual, Rev. 0 Page 12 07/31/13
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 IT'S 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.
R E V 1 . 0 0
3. The present frequency and gain of the downconverter is shown.
F=1000 G=+25.0
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.
2016-0510 Manual, Rev. 0 Page 13 07/31/13
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 12 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 = 1000 R
Pressing the Up/Down switch down will toggle the display to:
F = 975 R
By using the horizontal rocker switch the cursor can be moved left or right .
F = 975 R
NOTE: CHANGES DO NOT TAKE PLACE ON FREQUENCY UNTIL YOU GO TO THE SAVE
MENU AND INDICATE YOU WANT TO SAVE THE CHANGES. THE CARRIER IS MUTED WHEN
FREQUENCY IS CHANGED.
When the display indicates the value desired you can push the Menu/Execute switch to get to the next item:
G = +25.0
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:
F=1000 G=+25.0
Figure 2.5 gives the menu items and how to make changes.
2016-0510 Manual, Rev. 0 Page 14 07/31/13
2.5.5 Gain Changes
When you get to this menu note that the gain changes will be made as you make them but if you do not wish to save the changes you have made, scroll to “R” and push the Menu/Execute switch and select “NO” in the
“SAVE SETTINGS?” window or do not press the Menu/Execute switch; simply do nothing for approximately 12 seconds, and the system will return to the normal operating mode.
To change the DOWNCONVERTER GAIN:
Push the Menu/Execute switch to get to the gain setting (See Figure 2.5 for the sequence of menu options):
G = +25.0
R
Pressing the Up/Down switch will change the gain in 1 or 10 dB steps depending on the cursor location:
G = +35.0
R
By using the horizontal rocker switch the cursor can be moved left or right. Pressing the Up/Down switch will toggle the display digit selected until you have the desired gain.
G = +35.0
R
NOTE: THE GAIN WILL BE CHANGED AS YOU ADJUST THE NUMBERS. HOWEVER, THE
VALUE WILL NOT BE STORED UNTIL YOU INDICATE YES IN THE SAVE SETTINGS
WINDOW.
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:
F=1000 G=+25.0
Figure 2.5 gives the menu items and how to make changes.
2016-0510 Manual, Rev. 0 Page 15 07/31/13

3.0 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 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.
