1-Port & 2-Port Impedance

Measure PDN and VRM output impedance — down to the micro-ohm level, from near-DC to hundreds of MHz. This is the data behind power-integrity, decoupling design and non-invasive (NISM) stability.

Works with any VNA or oscilloscope. Buy the parts you need below, or request a quote for the full setup.

What you need to make this measurement
VNAAny VNA or Oscilloscope — measures impedance vs frequency
CoreP2102A 2-Port Probe — 2-port shunt-through probe for micro-ohm PDN impedance (1× for <5 V)
CoreJ2102B Common-Mode Transformer — ground-loop isolator that makes the low-impedance 2-port measurement possible
OptionalP2104A 1-Port PDN Probe — easy-to-land ripple probe with longer pins; various attenuations
OptionalP2105A Power-Rail, TDR & Impedance Probe — lowest-noise 1-port probe for ripple / PDN
OptionalJ2114A High-CMRR Isolation Amplifier — for impedances below ~100 µΩ
OptionalPort Saver DC Block — protects your instrument at voltages above 5 V
