● Bus Health 모드를 이용하여, 장비에 입력된 Bus의 정상값과 비교하여 Bus의 상태를 측정합니다. 일부 유저들은 전체신호의 상태를 검사하기 위해 ‘Eyepattern’ 모드를 사용하기도 합니다.
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.
well within limits = ‘good’, gives green tick mark
within specified percentage of the limit values = ‘weak’, gives orange tickmark
beyond limit values = ‘bad’, gives red tickmark
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.

Waveform Parameter analysis with automatic read-out and parameter validation (good / weak / bad); test limits are based on industry standards or may be set by the user.
Eyepattern display mode.
Measured parameters (where applicable):
bias voltage level,
pulse width or baud rate,
Eyepattern display mode:
Gives waveform display of bus signals with user selectable persistence of the display. Timebase, attenuator and persistence settings may be altered by the user.
