What is TDR cable tester?
A time-domain reflectometer (TDR) is an electronic instrument used to determine the characteristics of electrical lines by observing reflected waveforms. It can be used to characterize and locate faults in metallic cables (for example, twisted pair wire or coaxial cable).
How do you measure cable length?
Multiply the current figure by the diameter of the wire; for example, if the diameter of the wire is 1.5 inches, this figure would be multiplied by 1.5. The final figure should give the length of the wire.
Is TDR accurate?
The TDR is an extremely accurate instrument. However, if cable system parameters and constants are in error, they might cause incorrect data interpretation. For the specific TDR case, knowing the parameters or propagation constants is imperative: they are necessary for any analysis of TDR signals.
When it comes to cable testing there are 3 types or 3 levels of testing what are they in order?
Depending on the task the field test instrument performs, it can be classified into one of the three hierarchical groups: certification, qualification, or verification.
