MODEL 2016-05A Downconverter
1.0 General
1.1 Equipment Description
2016-05A L-Band Downconverter converts 950 to 1525 MHz to 140 MHz in 1 MHz steps with low group
delay and flat frequency response. The 2016-05A Input and Output levels have been optimized to support
transmit from an L-band modem to a 140 MHz IF upconverter. Multi-function 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). The gain is adjustable from 0 to +50 dB. Remote operation allows
selection of frequency and gain. Parameter selection and frequency and gain settings appear on the LCD
display. Standard connectors are BNC female for IF output and the optional external reference input and
reference output, and Type F female for the RF input. A high stability (±0.01ppm) reference, LNB +24 VDC,
0.4 Amps power and 10 MHz reference (includes a 10 MHz output connector), are available Options. The unit
is powered by a 100-240 ±10% VAC power supply, and housed in a 1.75” X 19” X 16” 1RU chassis.

2.0 Installation
2.1 Mechanical
The 2016-05A consists of one RF/Controller PCB housed in a 1 RU (1 3/4 inch high) by 16 inch deep chassis.
A switching, ±12, +24, +5 VDC power supply provides power for the assemblies. The 2016-05A can be
secured to a rack using the 4 holes on the front panel. Figure 2.1 shows how the 2016-05A is assembled.

2.4 Operation
2.4.1 Installing and Operating the 2016-05A Downconverter
1. Connect a -20 dBm to -70 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 to AC on the back panel.
4. Set the input frequency (See Section 2.5 Menu Settings).
5. Set the gain for +00.0 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. Option L only - To insert LNB +24 VDC on the RF center pin install 0.5A fast blo fuse in F1 and check
that DS8 lights yellow (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 2.4. 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, 1dB steps)
Menu 3 Set Unit to Remote Operation
Menu 4 Select External 10 MHz Ref (option E)
Menu 5 Select Reference Out (option E)
Menu 6 Set Remote mode (option Q)
Menu 7 Set RS-485 address (option Q)
Menu 8 View PCB Temperature (option T)
Menu 9 View LNB Current (option L)
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.
2016-05A Manual, Rev A Page 11 04/17/17

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=1350 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.
2016-05A Manual, Rev A Page 12 04/17/17

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=1350
R
Pressing the Up/Down switch down will toggle the display to:
F=1450
R
By using the horizontal rocker switch the cursor can be moved left or right .
F=1450
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:
SAVESETTINGS? YN
Selecting Ywill save the new settings. Selecting Nwill revert to the previous settings.
Pushing the Menu/Execute switch then takes you to this:
F=1450 G=+25.0
Figure 2.5 gives the menu items and how to make changes.
2016-05A Manual, Rev A Page 13 04/17/17

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=+15.0
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=+15.0
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.
When the display indicates the value desired you can push the Menu/Execute switch to get to the next
item:
OTHER? YN
R
OR you can scroll to “R” and push the Menu/Execute switch to get to:
SAVESETTINGS? YN
Selecting Ywill save the new settings. Selecting Nwill revert to the previous settings. Pushing the
Menu/Execute switch then takes you to this:
F=1450 G=+15.0
Figure 2.5 gives the menu items and how to make changes.
2016-05A Manual, Rev A Page 14 04/17/17

2.5.5 Alarm Indications
An alarm condition for will occur if any local oscillator phase lock loop (PLL) comes out of lock. The Mute
LED will light if you select Mute and the Remote LED will light when you select the Remote mode.
