SXT register setup procedure

5.2.2.

TRF tab setup

The TRF tab controls the TX RF gain and output path. By default the Tx RF gain is set to
maximum and TX1 is selected as the output path. For this test, we are not going to change these
settings.

5.2.3.

TBB tab setup

In the TBB tab the baseband gain and filter bandwidth are controlled. Follow the instructions
below set up TBB:

Select the

A/SXR

to control channel A.

Set Frontend gain and reference bias current of IAMP.

Configure the base band filter settings.

Select the analog input path

to current amplifier

See Figure 12 below to check selections.
