16.2.7 Troubleshooting
If the calibration or measurement does not show meaningful results, the following table
helps you to find the cause.
Issue Checks
Calibration No waveform is visible. Check the cabling.
Check the pulse source.
Calibration Calibration with short failed Check the cable length: 0.5 m < length < 3 m
Use cables with low loss.
Use a short that has a low impedance for high frequen-
cies.
Calibration Calibration with open failed Use cables with low loss.
Calibration Calibration with match failed Use cables with low loss.
Use match with 50
Ω±
10% for single-ended measure-
ments.
Calibration Calibration with through failed Use cables with low loss.
Check the cable length: 0.5 m < length < 3 m
Calibration Failure after completion of all
calibration steps Use cables with low loss.
Check the pulse source.
Measurement Waveform is noisy or unstable Evaluate the calibration results for any resonances or
high attenuation in frequency response.
Increase averaging.
Reduce bandwidth.
Disable calibration. If noise disappears, reduce attenua-
tion or remove resonances from your setup and recali-
brate.
