MODEL 3016-2124-Downconverter 1.0 General 1.1 Equipment Description The 3016-2124 Downconverter converts 21 to 24 GHz to 70 ± 18 MHz in 125 kHz steps (1 kHz opt -X1008). This unit combines a multi-band block downconverter with a 3-4 GHz to 70 MHz agile downconverter to obtain the wide tuning range. Synthesized local oscillators (LO) provide frequency selection. Multi-function switches select the input frequency, gain, and other parameters.

1.4 Environmental Use Information A. Rack-Mounting - To mount this equipment in a rack, please refer to the installation instructions located in the user manual furnished by the manufacturer of your equipment rack. B. Mechanical loading - Mounting of equipment in a rack should be such that a hazardous condition does not exist due to uneven weight distribution. C.
2.0 Installation 2.1 Mechanical The 3016-2124 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 3016-2124 can be secured to a rack using the 4 holes on the front panel. Figure 2.1 shows how the 3016-2124 is assembled. POWER SUPPLY •••••••• ••••••••••••••• FIGURE 2.1 3016-2124 Mechanical Assembly 3016-2124- Manual_Rev.

2.4 Operation 2.4.1 Installing and Operating the 3016-2124 Downconverter 1. Connect a -50 dBm to -30 dBm signal to RF IN, J2 (Figure 2.2, page 10). 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, page 16). 5. Set the gain for 0.0 to +30.0 dB (See Section 2.5 Menu Settings, page 16). 6. Be sure DS6 (green, DC Power) is on and DS3 (red, Alarm) is off (Figure 2.3, page 10). 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 2.5): Power Up Normal Display Menu 1 Menu 2 Menu 3 Menu 4 Menu 5 Menu 6 Menu 7 Menu 8 Frequency in MHz Gain (0.0 to +30.
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 ITS 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 downconverter is shown. F = 23123.
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: 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 30 seconds, and the system will return to the normal operating mode. To change the 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.
