Channel
Use Internal ISI Check this option to add to the signal the internal ISI generated by the M8020A. To adjust the ISI value click on the
Customize button.
Customize Clicking on the Customize button will open the “ISI Channel Customization” dialog (see
Figure 9
). In this dialog, the
ISI channel is defined by setting one insertion loss point. The ISI channel can be configured separately for each data rate.
Clicking the Calibrated button sets the insertion loss point to the value used in the latest calibration available (if there
is one).
Clicking the Standard button sets the insertion loss point to the recommended values.
Figure 9 ISI Channel Customization
Note: This option is only available when the M8020A JBERT is used as the data generator.
Error Detector
Use full auto align The "Use full auto align" check box forces the use of AutoAlign on the error detector every time the sample point is
adjusted. Without it TimeCenter is used instead.
TimeCenter is a lot faster than AutoAlign. When the DUT transmits a good signal both work equally well. Forcing
AutoAlign is useful for testing DUTs that transmit a signal with a deformed eye shape or not properly centered
around 0 V.
Error Detector > InfiniiSim
Rx Calibration Settings Opens a window where the user can control embedding of a custom channel during receiver calibration by setting paths
to .tf4 files.
Tx Test Settings Opens a window where the user can control embedding of a custom channel during transmitter tests. It is a direct
mapping of the options available in the transmitter test app.
