2.4  Installation / Operation

2.4.1  Installing and Operating the 2083-914A Frequency Translator

1. Connect  a -10 dBm to -20 dBm signal to IF IN, J4 (Figure 2.1).
2. Connect the IF OUT, J5, to the external equipment.
3. Connect 100-240 ±10% VAC, 47 - 63 Hz to AC connector on the back panel.
4. Set the desired frequency translation mode ( 95 > 140 or 140 > 95) (See Section 2.5 Menu Settings).
5. Set the 140 MHz end frequency (IF IN or IF OUT) (See Section 2.5 Menu Settings).
6. Set the actual input level used ( -10 to -20 dBm) (See Section 2.5 Menu Settings).
7. Set the attenuation for 0 to 10 dB (See Section 2.5 Menu Settings).
8. Be sure DS6 (green, POWER) is on and DS2 (red, ALARM) is off (Figure 2.2).
9. 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 2.3. There is a spare fuse in the near slot. If a fuse 
continues to open, the power supply is most likely defective.
