This short video discusses the feature set your cabling needs to get PDN impedance measurements correct.
A coaxial instrument cable must do five things well:
Accurately get the signal from the source to the instrument without distortion
Provide the lowest possible cable shield resistance to minimize ground loop errors
Maximize the shield attenuation to limit noise
Be ultra-flexible so as not to rip the capacitors off the board
Support environmental qualification testing
Along with PDN Cable, Picotest has all the accessories and training you need to make accurate power integrity measurements.
