2.7 Installation/Operation
Installing and Operating the 4115-41-212 Ka-Band Upconverter
1. Connect a -40 dBm to -15 dBm signal to L-BAND INPUT, (Figure 2.5).
2. Connect the RF OUTPUT, to the external equipment.
3. Connect 100-240 ±10% VAC, 47 - 63 Hz to AC In connector on the front panel.
4. Be sure DS1 (green, DC Power) is on and DS2 (red, Alarm) is off (Figure 2.5).
5. Set the gain for +30 to 0 dB insuring that the output level is always in the range of -15 to 0 dBm.
6. Select either INT (for internal 10 MHz ref), AUTO (for internal 10 MHz ref UNLESS an external
10 MHz, +2 to +8 dBm signal is connected to J2), or EXT (for external 10 MHz, +2 to +8 dBm
reference that is inserted at J2) on front panel switch S1 (Figure 2.5).
7. Check that a 10 MHz, signal is present at the 10 MHz REF OUTPUT at the same level as the input,
±0.5 dB. (J4 - Figure 2.5).
8. AC Fuse - The fuse is a 1.25” x .25”- 1.0 amp (slow blow) and is inserted in the fuse F1 position.
NOTE: If a fuse continues to open, the power supply is most likely defective.
