Use this table to troubleshoot problems on a measurement :
Measurement
Description
Diagnosis
High Input Level
Measurement of the signal high level
Termination problem (load too light)
Cable length not compliant with standard
Faulty junction connection (oxidation, bad
contact, etc.)
Significant noise (check the cable route, ground
braid not connected, faulty chassis-ground, etc.)
…
Low Input Level
Measurement of the signal low level
Time Rise
Rise time
Cable length not compliant with standard
Unsuitable or damaged cable (the rise and fall
times increase with the cable impedance)
…
Time Fall
Fall time
Bit Time
Time of a bit
Cable length not compliant with standard
Unsuitable or damaged cable
Significant noise (check the cable route, ground
braid not connected, faulty chassis-ground, etc.)
…
DCD
Measuring duty cycle between
positive and negative pulses
Measurements made from a
combination of positive and negative
pulses
