2Replace the XMTR B 15 dB pad with a 5 dB pad.

3Install the SG2-DRT-3X board in the return configuration location on the lid board as illustrated in Figure 5.

4Ensure that the PIC cable is properly connected to the lid and E-pack connectors.

5Install the two RF cables from DRT MCX 1 and DRT MCX 2 to RF INPUT A and RF INPUT B respectively on top of the SG2-DRT-3X.

6Confirm that the green LED (ON) located on the top panel of the SG2-DRT-3X is illuminated to confirm enable status. A delay of approximately 10 seconds before illumination is normal.

7Review return-path system levels:

Each input of the SG2-DRT-3X is configured to drive the laser to the recommended level of +15 dBmV.

Use TP DRT1 and TP DRT2 (Figure 5) to monitor the levels of the segmented ports. Pad DRT1 and pad DRT2 are used to adjust the level into the transmitter.

Use TP XMTR B to monitor the levels of the two combined ports. Pad XMTR B is used to adjust the level into the transmitter.
