The second graphics display of the measurement report shows the modulation within the burst. The
modulation used during the measurement is always Fig31. Recording starts at bit position -38. It can
be clearly seen that still no burst is being received by the tester. Then follows the sync field including
the preamble for time synchronization between FP and PP. This field is followed by the A-field, which
differs from the surrounding fields in longer 0s and 1s sequences. The longest part is the B-field with
the long 1s and 0s bit sequence in its middle that is typical for Fig31. The burst is terminated by the X-
field (CRC). The end of the burst is reached at bit position 424. However, recording only stops at bit
position 462.
The frequency offset signaled by the CTS is displayed with a yellow line in the graphics. The tolerance
fields for the B-field modulation are marked by two red lines.
