Use this table to troubleshoot problems on a measurement :
Measurement
Description
Diagnosis
VHigh
Measurement of the signal high level
Termination problem
Cable length not compliant with standard
Chassis-ground disturbance problem
Significant noise (check the cable route, ground
braid not connected, faulty chassis-ground, etc.)
…
VLow
Measurement of the signal low level
TRise
Rise time between 10% and 90% of
the signal amplitude
Cable length not compliant with standard
Unsuitable or damaged cable (the rise and fall
times increase with the cable impedance)
…
TFall
Fall time between 90% and 10% of
the signal amplitude
Time Data
Measurement made using the bit time
total
Cable length not compliant with standard
Unsuitable or damaged cable
Significant noise (check the cable route, ground
braid not connected, faulty chassis-ground, etc.)
