MODEL 2015-27 Upconverter

1.0 General

1.1 Equipment Description

The 2015-27 Upconverter converts 70 ± 18 MHz to 2500 to 2700 MHz in 1.0 MHz steps (0.125 MHz steps optional) with low group delay and flat frequency response. Synthesized local oscillators (LO) provide frequency selection. 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), Remote operation (yellow) or the

TX carrier is Muted (yellow). Variable attenuators for the IF input and output provide a gain range of -10 to +30 dB as adjusted by the front panel multi-function pushbutton switches. 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 input, e xternal reference input, and RF output. The 2015-27 is powered by a

100-240 ±10% VAC power supply and is housed in a 1 3/4” X 19 “ X 16” rack mount chassis.

2.4 Operation

2.4.1 Installing and Operating the 2015-27 Upconverter

1. Connect a -40 dBm to -10 dBm signal to IF In, J4 (Figure 2.2)

2. Connect the RF OUT, J5, to the external equipment

3. Connect 100-240 ±10% VAC, 47 - 63 Hz to AC1 on the back panel.

4. Set the desired output frequency (See Section 2.5 Menu Settings).

5. Set the input level (See Section 2.5 Menu Settings).

6. Set the gain for -10 to +30 dB. Make sure the output stays within -20 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).

7. Be sure DS6 (green, DC Power) is on and DS2 (red, Alarm) is off (Figure 2.3).

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 Input Lvl (Set from -40 to -10)

Menu 3 Gain (-10 to +30)

Menu 4 Mute

Menu 5 Set Unit to Remote Operation (NOTE: the local controls still function when in REMOTE)

Menu 6 Select External 10 MHz Ref (option E)

Menu 7 Set Remote Mode (option Q)

Menu 8 Set RS-485 Address (option Q)

Save Menu When “R” is selected or at the 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.

2015-27 Manual, Rev A Page 13 12/17/08

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 and gain of the upconverter is shown.

F=2350 G=+10.0

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.

2015-27 Manual, Rev A Page 14 12/17/08

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 upconverter frequency:

F = 2650 R

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

F = 2640 R

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

F = 2640 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 = -20 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=2640 G=+00

Figure 2.5 gives the menu items and how to make changes.

2015-27 Manual, Rev A Page 15 12/17/08

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.

The following display is for changing the upconverter input level. This is an important setting to optimize spurious and should be made as accurately as possible:

INLVL = -20 R

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.

Pressing 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 R

Pressing the Up/Down switch to change the gain in 1 or 10 dB steps and then push the Menu/Execute switch to get to the Gain setting:

G = +20 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 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=2640 G=+10

Figure 2.5 gives the menu items and how to make changes.
