Turn the Keysight E5061B VNA you already own into a complete power integrity test bench.
One instrument. Six power integrity tests — each enabled by Picotest probes, injectors, and fixtures:
• Component testing & modeling — CTF
• PDN impedance — P2104A / P2102A
• VRM impedance — J2113A, J2102B
• PSRR — J2120A, J2121A, P2124A
• Stability, Bode — J2101A, J2110A
• NISM support — P2102A, P2105A, NISM software

Measuring loop stability usually means breaking the loop. It doesn't have to.
The Keysight E5061B ENA, paired with Picotest's P2102A 2-Port Probe and NISM, measures stability non-invasively — phase margin and effective-Q straight from the output impedance, nothing to cut or inject into the feedback path.
And stability is just one of six power-integrity tests one E5061B can run:
• Component testing & modeling • PDN impedance • VRM impedance • PSRR • Bode stability • NISM
One VNA you already own. Probes, injectors and fixtures from Picotest do the rest.

The best power integrity test equipment doesn't fall off the back of a truck — it comes from Picotest. Probes, signal injectors, and transient load steppers for engineers who take PDN validation seriously. No back alley required. Link in comments.

AI at scale demands more than compute power — it demands cleaner, more reliable power delivery.
This article explores how embedded capacitance materials can help address power integrity challenges in advanced AI systems, supporting faster, denser, and more efficient designs.

Powering AI at Scale with Embedded Capacitance Materials - Picotest As AI, cloud computing, and data centers continue to scale, so do their power demands—and the complexity of the systems that support them. These next-generation architectures rely not only on advanced chips, but also on high-performance connectivity and advanced interconnect solutions that enable ...
Can we borrow your brain? 🧠
We've built a tool to help you find the right test setup — based on what you're measuring (impedance, PSRR, stability, ripple/noise, TDR…) and the instruments you already have (Bode 100/500, a scope, another VNA).
We've tested it in-house, but you're the real experts. Give it a go and tell us: does it point you to the setup you'd actually reach for?
👉 https://www.picotest.com/find-your-test-setup/
It's made for a niche — power and signal integrity engineers — so your technical feedback genuinely shapes where this goes. Comment or DM, we're all ears.

Tony Ambrose from Tektronix previews SEPIA, Scope Embedded Power Integrity Analysis, a new measurement technique designed for today’s nonlinear, time-variant DC-DC converters on a Tektronix 6 Series Oscilloscope. Rather than relying on traditional frequency-domain Bode plots, SEPIA extracts phase margin, equivalent circuit models, and stability insight directly from a high-speed step load response.
This video gives a quick look into why step load response is superior to traditional Bode plots and shows how power integrity measurement is evolving.

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.

Why the Picotest S2000 Load Stepper ended up on the benches behind today's highest-current designs:
— Fast current edges that excite real PDN impedance behavior, not just the low-frequency portion an electronic load can reach
— Ability to test power rail crosstalk
— Programmable step amplitude and timing, repeatable enough to correlate simulation to measurement instead of arguing with it
— Directly stimulates the rail under test, no probe-loop interpretation games
The reason it's in the hands of the teams behind today's most demanding power-delivery designs isn't marketing. It's that you can't validate a 2000A+ multi-phase multi-rail setup with a tool built for laptop SMPS — and the engineers responsible for those rails figured that out first.
If the stimulus side of your bench is what's limiting your confidence in the result, DM the man who built it and we will support the solution. Steven Sandler.

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.

The recurring theme: PDN measurements in high-current, fast-switching environments fail quietly. The waveform looks fine. The numbers look fine. The setup is the problem.
