MODEL 2016-03A L-band Downconverter 1.0 General 1.1 Equipment Description The 2016-03A L-band Downconverter converts 950-1525 MHz to 70 (±18) MHz in 1 MHz steps with low group delay and flat frequency response. The 2016-03A Input and Output levels have been optimized to support transmit from an L-band modem to a 70 MHz IF upconverter. Multi-function push button switches select the RF frequency, gain, and other parameters.

1.3 Monitor and Control Interface A) Remote serial interface Protocol: RS-232C, 9600 baud rate, no parity, 8 data bits, 1 start bit, and 1 stop bit.
C) Status Requests Table 1.2 lists the status requests for the 2016-03A and briefly describes them. * PLEASE NOTE: The two character {aa}(00-31) prefix, in the table below, should be used ONLY when RS-485, (OPTION-Q), is selected. TABLE 1.
B) Commands - Table 1.1 lists the commands for the 2016-03A and briefly describes them. After a command is sent the 2016-03A sends a return “>” indicating the command has been received and executed. General Command Format - The general command format is {aaCND...
1.4 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.
2.0 Installation 2.1 Mechanical - The 2016-03A 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 201603A can be secured to a rack using the 4 holes on the front panel. Figure 2.1 shows how the 2016-03A is assembled. POWER SUPPLY FIGURE 2.
2.2 Rear Panel Input/Output Signals - Figure 2.2 shows the input and output connectors on the rear panel. AC - POWER IN AC input for switching power supply. 100-240 ±10% VAC, 47-60 Hz. F1 - LNB FUSE (option -L) 0.5A, Fast Blo, 1/4” Fuse; installing fuse places +24 VDC, 0.5 Amps, max on the RF IN (J2 center pin). J2 - RF IN 950-1525 MHz input -70 to -20 dBm see Table 2.2. J1 - IF OUT 70 MHz output -20 to -30 dBm See Table 2.2. J10 - MONITOR AND CONTROL DB9 female connector See Table 2.
2.3 Front Panel Controls and Indicators - The following are the front panel controls and indicators. DS3 - DOWN ALARM LED Red LED indicates downconverter alarm. DS1 - REMOTE LED Yellow LED indicates remote operation. LCD DISPLAY Display shows Downconverter frequency in MHz and Gain in dB F=1525 G=+25.0 S1 - MENU/EXECUTE BUTTON Press this to get into Program mode and to execute any changes. MENU EXECUTE ALARM REMOTE DS6 - POWER LED Green LED indicates presence of DC power. POWER S2 - VERT.
2.4 Operation 2.4.1 Installing and Operating the 2016-03A 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.
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.
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. REV1.00 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.
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.
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.
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.
