5.14 Link Settings
The Link options panel allows you to manage links (see Figure 5.11 ). You can define the
basic link parameters or leave it on Auto detect. The various link settings are described in
this section (See
Figure 5.1 on page 54 : 3).

5.14.1 Speed
The Speed can be set at Auto, 8.0 GT/s, 5.0 GT/s, or 2.5 GT/s from the drop‐down menu.
The default is Auto (see
Figure 5.1 on page 54 : 3A).
Auto: When set to Auto, Teledyne LeCroy’s embedded software auto‐determines the
speed.
8.0 GT/s, 5.0 GT/s, or 2.5 GT/s: When set to a specific speed Teledyne LeCroy’s software
forces the hardware to record at that speed.
For Auto speed setting to work the polarity setting of lane 0 has to be correct. The
polarity can be set manually if the link is already in L0 state, or, for automatic polarity
detection, the bus has to go through a training sequence so the analyzer can track the
polarity.
Note: For certain build configurations 5.0 GT/s, 8.0 GT/S and raw recording speed is disabled.
