MODEL 2017-36 Up/Downconverter

1.0 General

1.1 Equipment Description

The 2017-36 Up/Downconverter converts 70 MHz to 950-1525 MHz (Up) and 2000-2500 MHz to 70 MHz

(Down) in 1 MHz steps 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 for up and downconverters

(red), remote operation (yellow), and upconverter mute (yellow). Gain is manually controlled over a –10 to +30 dB range for the upconverter and over a 0 to +50 dB range for the downconverter as adjusted by the front panel multi-function push-button 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 and the optional external reference input and output, and Type F female for RF. LNB or SSPB +24 VDC and 10

MHz reference can be inserted on the RF lines as added options. A high stability (±0.01ppm) option is also available. The unit is powered by a 100-240 ±10% VAC power supply and housed in a 1.75” X 19“ X 16” rack mount chassis.

Save Menu At the end or when “R” is selected from any of the above menus

Alarm indications appear on the LEDs (see figure 2.2).

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.

2017-36 Manual, Rev A Page 12 9/29/08

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.

R E V 1 . 0 0

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

U F=1445.000 G=+10

D F=2250.000 G=+25

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, input level 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.

2017-36 Manual, Rev A Page 13 9/29/08

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 2.4 for the sequence of menu options). The following display is for changing the upconverter frequency:

UP F = 1450.000

R

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

UP F = 1350.000

R

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

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 the next item:

UP 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.

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 the :

U F=1350.000 G=+10

D F=2250.000 G=+25

Figure 2.4 shows all the menu items and how to make changes.

2017-36 Manual, Rev A Page 14 9/29/08

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.

2.5.5.1 Upconverter Gain

To set the upconverter 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 2.4 for the sequence of menu options.

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:

UP INLVL = -20 R

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:

UP G = +10 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 A 0 dBm OUTPUT LEVEL.

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 the :

U F=1350.000 G=+00

D F=2250.000 G=+25

Figure 2.4 shows all the menu items and how to make changes.

The following display is for changing the downconverter gain. This is an important setting to optimize spurious and should be made as accurately as possible to provide an output in the -20 to 0 dBm level range:

DN G = +15 R

Pressing the Up/Down switch to change the level in 1 or 10 dB steps. 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
