We have a lot of information on our website about PDN validation using dynamic stepload testing and transient load current steppers. If you want to search the articles by Video, Product, or Article - even understand how we quote such a complex tool for your specific requirements - take a look at our Insights.

Your simulation says the power integrity and PDN impednace is fine. Your hardware says otherwise.

The mismatch usually traces back to one place: the capacitor and ferrite bead models you're using were never measured properly.

The new Picotest Component Test Fixture (CTF), paired with the Bode 100 or Bode 500 VNA, or other VNA, gives you impedance and S-parameter measurements up to 3 GHz with pH-level fidelity — accurate enough to extract ESL, ESR, and full equivalent circuits that actually correlate with what's on your board.

What that earns you:

→ More Accurate simulation (SPICE/ADS/Simplis) models built from real measurements, not vendor datasheets
→ Better-targeted decoupling — smaller BOM, less board area
→ Confident PDN simulation from DC into the GHz range
→ Fewer late-cycle EMC and stability surprises

Designed specifically to solve the calibration limitations of the Bode platform.

What’s New for Bode 100 & Bode 500 Users - Picotest The OMICRON Lab Bode 100 and the newer Bode 500 VNAs have evolved significantly over the past 1–2 years. Combined with new Picotest accessories, software enhancements, and application workflows, today’s Bode platform supports measurements and modeling capabilities that previously required multip...

AI data centers are pushing power delivery networks past where typical measurement setups can keep up. Massive currents, fast transients, and a probing system that can quietly lie to you if probe flatness, CMRR, or ground loops aren't handled correctly.

On Wednesday, May 13, Picotest's Steve Sandler and Tektronix's Seamus Brokaw team up for a Tech Briefs webinar on the hidden measurement errors that distort power integrity validation — and the practical techniques that fix them.

What you'll take away:
– Common measurement errors that affect PDN validation
– How probe flatness, CMRR, and noise change what your waveform actually shows
– Techniques to reduce ground loops and measurement noise
– Best practices for reliable PDN measurement in AI data center systems

45 minutes + live audience Q&A. Two sessions so you can pick your time zone:
Session 1 — 8:00 AM PDT / 5:00 PM CEST (EMEA-friendly)
Session 2 — 5:00 PM PDT / 8:00 AM CST, May 14 (APAC-friendly)
