Bus Health Test

Verifies the electrical parameters of industrial bus systems using automatic measurement and analysis functions. Next to that, an Eyepattern mode is provided for visual inspection of signal quality.

Parameter Classification
Default Values

• Well within limits + 'good', gives green tick mark.
• Within specified percentage of the limit values = 'weak', gives orange
  tick-mark.
• Beyond limit values = 'bad', gives red tick mark.

Note: Limits values, as a default, are based on industry standard for the selected bus type or may be set by the user. The tolerance band  (percentage) taken into account for the classification 'weak' may be altered by the user.
