215C:

100 MHz

Sample rate:

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 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.

of the display. Timebase, attenuator and persistence settings may be
altered by the user.

Persistence modes:

off – short – medium – long – infinite
