It allows you to configure the loop bandwidth of the analyzer CDR. Note
that the value introduced here will be used for HS-G1 tests (see Figure ).
For other gears, the bandwidth is automatically calculated as a multiple
(x2 for G2, x3 for G3 and x4 for G4). To directly modify the CDR Loop BW
value for each gear, use the CDR Loop Band wid th - Top Level property
that is accessible in the Property panel of the main windows when
