MODEL 3016-1520-1200 Downconverter
1.0 General
1.1 Equipment Description
The 3016-1520-1200 Downconverter converts 15 to 20 GHz to 1200 ± 50 MHz in 125 kHz steps (1 kHz opt-
X1008). The 15 to 20 GHz is first converted to 7.0 GHz with an agile, high side LO and then to 1200 MHz to
obtain the wide tuning range. Synthesized local oscillators (LO) provide frequency selection. Multi-function
switches select the input frequency, gain, and other parameters. Front panel LEDs provide indication of DC
power, PLL alarm or Remote operation. Gain is adjustable manually (MGC) over a +10 to +30 dB range. The
frequency and gain are remotely selectable. Parameter selection and frequency and gain settings appear on the
LCD display. Connectors are SMA female for the RF, and BNC female for the IF and external 10 MHz
reference input and output. Other connector options are available. It is powered by a 100-240 ±10%VAC
power supply, and is in a 1 3/4” X 19” X 18” rack mount chassis.

1.4 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 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.

2.4.1 Installing and Operating the 3016-1520-1200 Downconverter
1. Connect a -50 dBm to -30 dBm signal, to RF IN, J2 (Figure 2.3, page 9)
2. Connect RF OUT, J5, to the external equipment.
3. Connect 100- 240 ±10% VAC, 47 - 63 Hz to AC input on the back panel.
4. Set the desired output frequency (See Section 2.5 Menu Settings, page 13).
5. Set the input level (See Section 2.5 Menu Settings, page 15).
6. Set the gain for -10.0 to +30.0 dB. Make sure the output stays within -15 to 0 dBm with the
gain selected and the input level provided. The firmware will prevent setting gain and
input level outside this range. (See Section 2.5 Menu Settings, page 15).
7. Be sure DS6 (green, DC Power) is on and DS2 (red, Alarm) is off (Figure 2.3, page 9).
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, page 10. 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, page 15):
Power Up
Normal Display
Menu 1 Frequency in MHz
Menu 2 Input Level in dBm (-50 to-30)
Menu 3 Gain in dB (+10 to +30.0)
Menu 4 Mute Signal
Menu 5 Set Unit to Remote Operation
Menu 6 Select Frequency Step Size -1kHz minimum (option X1008)
Menu 7 Select External 10 MHz Reference
Menu 8 Select RS232, RS422, or RS485 Remote Operation (option Q)
Menu 8 Select RS485 Remote Address for Unit (option Q)
Save Menu When “R” is selected in any of the above menus or when operator reaches the end
Alarm indications appear on the LEDs (see figure 2.2, page 9).
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.
3016-1520-1200 Manual_Rev. B Page 14. 12/11/19

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.
REV 1.00
3.The present frequency, gain, and selected RF output of the Downconverter is shown.
F = 19123.125
G = +10 REF = INT
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 as Mute on/off, the vertical switch will alternately turn the function
on or off regardless of the direction operated.
3016-1520-1200 Manual_Rev. B Page 15. 12/11/19

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:
1.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 = 19123.125 R
Pressing the Up/Down switch down will toggle the display to:
F = 19123.125 R
By using the horizontal rocker switch the cursor can be moved left or right .
F = 19123.125 R
NOTE: CHANGES DO NOT TAKE PLACE ON FREQUENCY UNTIL YOU GO TO THE SAVE
MENU AND INDICATE YOU WANT TO SAVE THE CHANGES. THE CARRIER IS MUTED
WHEN FREQUENCY IS CHANGED.
When the display indicates the value desired you can push the Menu/Execute switch to the next item:
INLVL = -20R
OR you can scroll to “R”, push the Menu/Execute switch to get to:
SAVE SETTINGS? Y N
Selecting Ywill save the new settings. Selecting Nwill revert to the previous settings.
Pushing the Menu/Execute switch then takes you to the default display:
F = 19123.125
G = +10 REF = INT
Figure 2.5 shows all the menu items and how to make changes.
3016-1520-1200 Manual_Rev. B Page 16. 12/11/19

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 GAIN, first push the Menu/Execute switch to get to the gain setting:
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 input level.
This is an important setting to optimize spurious and should be made as accurately as possible:
INLVL = -20R
NOTE: CHANGES TAKE PLACE ON LEVEL AND GAIN IMMEDIATELY BUT DO NOT GET
SAVED UNTIL YOU GO TO THE SAVE MENU AND INDICATE YOU WANT TO SAVE THE
CHANGES.
Press the Up/Down switch to change the level in 1 dB steps and then push the Menu/Execute switch to
get to the Gain setting:
G = +10.0 R
Press the Up/Down switch to change the gain in 0.1, 1 or 10 dB steps:
G = +20.0 R
By using the horizontal rocker switch the cursor can be moved left or right. Pressing the Up/Down
switch down will toggle the display digit selected until you have the desired gain.
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. DO NOT SET A GAIN THAT WOULD EXCEED 0 dBm OR HAVE LESS THAN -20 dBm
OUTPUT LEVEL. THE FIRMWARE PREVENTS YOU FROM THIS.
When the display indicates the value desired you can push the Menu/Execute switch to the next item
OR you can scroll to “R”, push the Menu/Execute switch to get to:
SAVE SETTINGS? Y N
Selecting Ywill save the new settings. Selecting Nwill revert to the previous settings.
Pushing the Menu/Execute switch then takes you to:
F = 19123.125
G = +10 REF = INT
Figure 2.5 gives the menu items and how to make changes.

2.5.5 Alarm Indications
An alarm condition for will occur if the local oscillator phase lock loop (PLL) comes out of lock. The Mute
LED will light if you select to mute the Tx Signal and the Remote LED will light when you select the Remote
mode.
2.5.6 10 MHz Reference Mode Operation
Internal Mode: The unit uses its own built-in 10 MHz OCXO. The Internal Reference is present on the
Reference Output Connector, J18. REF = INT appears on the front panel display.
External Mode: The unit uses a 10 MHz Reference that is connected to the External Reference Input, J3.
REF = EXT appears on the front panel display. The External 10 MHz Reference level
must be +3dBm, ±3dB. If the External 10 MHz signal does not meet the unit’s
specified parameters then the unit will not function properly. The External Reference
is present on the Reference Output connector, J18.
Auto Mode: The unit defaults to the External 10 MHz Reference as long as the level meets the +3dBm,
±3dB specification. REF = AUTO - E appears on the front panel display where the -E
indicates that the unit is using the External 10 MHz Reference. The External Reference is
present on the Reference Output connector, J18.
If the external 10 MHz Reference signal level is less than -1dBm, the unit switches to
Internal 10 MHz Reference. REF = AUTO -I appears on the front panel display
where -I indicates that the unit is using the Internal 10 MHz Reference. The Internal
10 MHz Reference is present on the reference output connector, J18.
