At Embedded World 2026, Tektronix presented something that did not look like a traditional oscilloscope demo. There was no waveform on a large screen, no eye diagram being explained to a crowd. Instead, there was a compact 1U rack unit sitting on a table, a Keithley 2450 SourceMeter next to it, and a laptop showing a configuration table.
What was on that table was the Tektronix MP5000 Series — a modular precision test system that represents a significant shift in how test and measurement equipment is being designed and sold.

What Is the MP5000 Series?
The MP5000 is a 1U modular mainframe that accepts plug-in measurement and source modules. The base unit — MP5103 — is a 3-slot low-profile chassis. Into those slots, engineers can configure:
→ HSMU80-2: MP5000 SMU Module, 30W, 60V, 1.5A, 2 channels
→ HPSU50-2ST: MP5000 PSU Module, 50W, 50V, 5A, 2 channels, Standard Power Supply
The Keithley 2450 SourceMeter displayed alongside showed what precision means in this context: 0.0008 nA current measurement, 0.0003 mV voltage measurement. These are not benchtop rough measurements — this is characterization-grade accuracy in a platform that can be automated and scaled.
Why Modular Matters
The modular approach solves a problem that has frustrated test engineers for years: the traditional test bench is rigid. You buy a power supply, a source measure unit, a precision multimeter — each in its own box, each with its own software driver, each requiring its own calibration cycle.
The MP5000 changes this in three specific ways:
Scalability
Start with the channels you need today. Add modules as your requirements grow. The same mainframe that supports a 2-channel SMU today can support a mixed SMU and PSU configuration tomorrow — without buying a new platform.
Automation
The MP5000 supports Python scripting and TSP (Test Script Processor), Tektronix's own scripting language. A complete test sequence — source a voltage, measure current, log results, step through a sweep — can run autonomously overnight without an engineer present. The Tektronix brochure at the booth described it directly: "automate with Python/TSP for high-throughput validation and production."
Integration
The system connects via LAN, enabling remote control and integration with larger automated test environments. For production test or reliability validation — where the same measurement must be repeated thousands of times — this is not a convenience, it is a requirement.

The Connection to Signal and Power Integrity
The Tektronix booth materials highlighted three strategic areas the MP5000 addresses:
→ Bridging Signal & Power Integrity — The 7 Series oscilloscope built for advanced HSS analysis, with new tools for precise channel modeling and system optimization. For power integrity, the MSO6B with high bandwidth power rail probes and IsoVu TICP probes provides highly accurate, isolated measurements on sensitive power rails.
→ The Essentials for Test & Design Engineers — Oscilloscope and real-time spectrum analyzer combinations covering automotive validation, EMI/EMC pre-compliance processes, and repeatable debugging workflows.
→ Scalable, Adaptable, Automated — The MP5000 itself: a compact 1U platform to mix SMU/PSU channels, scale in minutes, and automate for high-throughput validation and production.
This three-part framing reveals Tektronix's strategy: they are not selling instruments. They are selling workflows — from design verification through production validation.
Why This Matters for Embedded System Developers
The engineers who need the MP5000 are not the same engineers who need a 16 GHz oscilloscope. They are the teams working on:
→ Power management IC characterization — measuring leakage currents in the nanoamp range, line regulation curves, load transient response
→ Sensor and analog front-end validation — where the device sensitivity requires sub-millivolt source accuracy
→ Battery and energy harvesting systems — where understanding the full I-V behavior of a source requires a source measure unit, not just a power supply
→ Production test automation — where the same measurement sequence must run reliably across hundreds or thousands of units
These are applications where a traditional benchtop setup hits its limits: too many boxes, too much cabling, too little automation capability, too slow.
The Broader Trend This Represents
The MP5000 is part of a pattern that was visible across multiple booths at Embedded World 2026. Test and measurement vendors are moving away from selling individual high-performance instruments toward selling integrated, software-driven measurement platforms.

The differentiator is no longer purely hardware specification. It is:
→ How quickly can the system be configured for a new application?
→ How easily can the measurement sequence be automated?
→ How seamlessly does it integrate with the engineering team's existing software environment?
A modular system that answers all three questions — and that can be scaled from a single-engineer bench to a multi-station production environment — has a fundamentally different value proposition than a fixed-configuration instrument.
The Keithley 2450 sitting next to the MP5000 was not accidental. Tektronix acquired Keithley in 2010, and the precision source-measure capability that Keithley pioneered is now being integrated into the modular architecture of the MP5000. The result is a platform that brings characterization-grade precision into a production-automation-ready form factor.
For embedded engineers who have outgrown the traditional benchtop setup — or who are building test infrastructure that needs to scale — the MP5000 represents a direction worth understanding.
