5.2.5 BUC Turn-on/off Sequence.

After the user software is installed on your PC, the following sequence can be used to turn on the

BUC.

1) Connect one end of a RF cable with a WR28 waveguide adapter to WR28 RF port on the

BUC and the other end of the RF cable to the antenna or a dummy load.

2) Connect one end of an IF cable to N-type IF connector on the BUC and the other end of the

IF cable to the output of the IF source or modem.

3) Connect one end of a MS 12-wires cable to MS 12-pins connector on the BUC. And connect

two wires out of the other end of the MS 12-wires cable, which are dedicated to DC power,

to a power supply with +48V DC or a level specified in the specification sheet in Section 3.1,

and four wires for Ethernet connection or three wires for RS232 connection out of the other

end of the MS 12-wires cable to the modem or your PC, and external Mute wire to a ground.

(Refer to Table 1 and Fig. 4 for connection details)

4) Turn on the power supply to supply +48V to the BUC.

5) Set up the serial mode or Ethernet mode connection according to Section 5.2.3 or 5.2.4.

6) Once your PC or modem is connected with the BUC using either serial or Ethernet mode,

check various BUC status such as Output power, Temperature, LO Lock, Over-temperature,

Over-power, Fan, and external mute.

7) Turn on the IF power source with a proper power level according to the BUC specification

sheet, which enters the IF input port of the BUC.

8) To turn on the SSPA, make sure that all of LO Lock, Over-temperature, Over-power, and

External Mute states should be green. Then click SSPA ON button on BUC GUI window.

9) Adjust the BUC gain using Gain setting buttons such as MAX GAIN, MIN GAIN, and specific

gain values on the BUC GUI window.

10) If all of LO Lock, Over-temperature, Over-power, and External Mute states are not green on

BUC GUI window, the SSPA does not turn on even though SSPA ON button is clicked.

During the operation, if one of LO Lock, Over-temperature, Over-power, and External Mute

states becomes red on BUC GUI window, the SSPA is automatically turned off.
