Effect of cable movement
Bumping cable
As you can see, your fixturing must be free from vibration. Bending cables during a test is another
NO NO. The above measurements were made on a single triax cable for classic parameter analyzers.
The Kelvin triax cable is less sensitive to movement (triboelectric effects). However, either cable
works fine to fA level if the cables are reasonably still...i.e. not swinging, coiled up and moved, etc.
