It's October and that means we have a month left to offer you the absolute BEST PRICE of the year...

The Power Integrity Bundle now includes the Component Test Fixture, so the measurements it covers are;

𝐂𝐨𝐦𝐩𝐨𝐧𝐞𝐧𝐭 𝐢𝐦𝐩𝐞𝐝𝐚𝐧𝐜𝐞 𝐚𝐧𝐝 𝐦𝐨𝐝𝐞𝐥𝐥𝐢𝐧𝐠 - characterize real capacitors and inductors under DC bias up to 75V, and build a SPICE model from the result.
𝐏𝐃𝐍 𝐚𝐧𝐝 𝐕𝐑𝐌 𝐨𝐮𝐭𝐩𝐮𝐭 𝐢𝐦𝐩𝐞𝐝𝐚𝐧𝐜𝐞 - 2-port shunt-through down to micro-ohms, plus NISM stability from the same sweep.
𝐂𝐨𝐧𝐭𝐫𝐨𝐥 𝐥𝐨𝐨𝐩 𝐬𝐭𝐚𝐛𝐢𝐥𝐢𝐭𝐲 (𝐠𝐚𝐢𝐧/𝐩𝐡𝐚𝐬𝐞) - the Bode plot, non-invasively, on a live supply.
𝐏𝐒𝐑𝐑 - line injection without disturbing the rail.

𝐓𝐡𝐞 𝐨𝐟𝐟𝐞𝐫: a further 10% off the probes, injectors, DC blocks and CTF inside the bundle, on top of the bundle discount, which is already our best price.

This runs once a year, so end-of-year budget goes furthest here. It won't be back for at least 11 months.
Contact us with your requirements and we'll add the 10% to your quote.

In July, Tektronix launched PDN Analysis Software for their 4, 5 and 6 Series B oscilloscopes. This
"Building on the Stability Evaluation for Power Integrity Analysis (SEPIA) methodology pioneered by Picotest, Tektronix is the first to embed SEPIA directly into an oscilloscope."
What that means at the bench: phase margin, damping characteristics, and an equivalent circuit model from a single step-load response — in as little as 500 microseconds. No injection transformer. No loop break. No board modification.
Steve Sandler is also on Tektronix's Ask the Experts power integrity panel, taking on three of the problems engineers actually get stuck on: PDN impedance sitting above target, regulator stability you can't confirm from a step response alone, and noise coupling where the model said it wouldn't. It's on demand — watch now: https://www.picotest.com/insights/steve-sandler-joins-tektronixs-power-integrity-expert-panel/

The software can only analyze what arrives at the probe tip, so two things still have to be right.
The step has to be fast, clean, and made at the rail rather than at the end of a cable: use → Load Stepper Probe S10 or S50 — lands directly on the rail, no fixture → S2000 Load Stepper board — for higher-current rails → J2111B or J2112A current injector — for small rails and low step currents.

And the probe has to see the response without adding to it: use → P2104A or P2105A low-noise 1× probe → J2115A isolator set to kill the ground loop → 3DPP-200 holders to hold it on the rail hands-free.

If you already have the scope, those are the two purchases between you and the measurement.

Picotest - Leading the way in transient load stepper technology
Load Slammer by Picotest — sub-ns load steps, 100 mA to 2,300 A

It's not just current — it's how fast. The Picotest Load Slammer platform steps real current at sub-ns edges, 100 mA to 2,300 A: injectors, probes, and in-socket steppers for the rails behind AI silicon.

We all know the rails got faster than the methods used to measure them.

These are the questions you are asking.

𝟎𝟏 My rail is over 1,000 A. Why can't I validate it the way I used to?
𝟎𝟐 How do I know the ripple I'm seeing is the rail and not ground bounce, a ground loop or common-mode noise?
𝟎𝟑 My Bode plot looks fine and I'm under target impedance, so why does the rail still ring on a load step?
𝟎𝟒 Can I measure large-signal impedance, fast transients and closed-loop stability on the scope I already have? 05 What's coming next for measuring modern power delivery networks?

SEPIA answers the stability one from a single load step. It reads phase margin, Q and an equivalent RLC model straight off the ringing, without breaking the loop or injecting a signal. It runs on your Tektronix MSO with Picotest load steppers and injectors, and Picotest or Tektronix probes.

And you can order the Tektronix side directly from us too.

Same load step, two time bases.
At ms/div you see a dip and call it good. At µs/div you see the loop — the overshoot, the ring, the recovery your controller is really doing.

If your step generator can't get you to µs/div, you're not measuring transient response. You're measuring an average.

A picohenry is a millionth of a millionth of a henry. You can't measure one directly — so how do you know it's there?

Steve Sandler opens with something deceptively simple: try to weigh a single feather. Set it on a lab balance and it won't sit still — air currents, static, even your breath move it more than it weighs. The thing you want to measure is smaller than everything disturbing it.

That's the whole game in extreme measurement, and it scales all the way down to the picohenry — roughly one micron of wire. Ignore it at DC and it's nothing. But V = L·di/dt: at a fast edge, that "nothing" becomes ~10 mV of noise on a sub-1V rail. At 1 GHz it's ~6.3 mΩ, blowing your milliohm target impedance.

So you reach for a precision component fixture, a VNA, careful high-frequency calibration and de-embedding. And here's the part that keeps me up at night:

You never actually measure the picohenry. You measure your fixture, model it, and subtract it — so the number on the screen is only as honest as that model.

👉 How far do you trust de-embedding before you stop believing the number? Where has it burned you?
