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.
