▪
Enable/Disable TX control for each channel (TX ON/OFF).
Once turned off, the control of
TX settings is disabled: channel control is locked from any selections, and TX output is
turned off (Figure 17).
▪
Specify the
TX signal pattern.
The supported TX patterns are all available in the dropdown
list, depending on the BERT model in use.
▪
Specify the TX amplitude.
In optimal mode, the slider shows the calibrated differential
peak to peak amplitude range, each displayed value is the combination of the optimal FFE
taps. Pre-Emphasis, Main, and Post-Emphasis taps are calculated during calibration.
Calibration is supported on low and high rates and on both eye modes (NRZ and PAM4). The
optimal FFE taps are currently calculated at scaling 80%.
▪
Specify Error insertion rate.
The actual rate of errors per second depends on architecture
capabilities (Figure 18).
To insert Errors:
▪
Enable Error Insertion mode
(the green
color indicates that error insertion feature is
enabled).
▪
Specify the Error Insertion Rate.

TX Control in Advanced Mode
While operating in Advanced Mode, you can fine-tune the transmitter signal with high
granularity. You will be able to specify the following TX settings and parameters:
