Saving configuration in a file
Once parameters have been configured, they can be kept in memory and saved in a
configuration file.
This configuration file can then be recalled in order to be recalled for future IPMD acqui-
sitions.
To save parameters in a configuration file:
No, Pass/Fail thresholds selected.
Pass/Fail analysis will be made upon defined thresholds: auto
values or delay.
Threshold delay values entered manually.
Threshold delay values automatically calculated according to
the bit rate info selection.
